Melissa number 3 for the bottom part I think you are talking about so here is how I got my answer. There are 2 equations that are in air bubbles since we don't know the distance we have to use the first one. we know the time is 3 seconds so 3 times 10 gives you how fast you are going which is 30 meters per second.
for part b of #3 you would take your distance divided by your time of three seconds to find out your average speed, distance can be calculated with d=5t^2. and for part c it gives you the equation d=5t^2, so you would just plug in your time of three seconds to get the distance to the bottom of the water
We were only supposed to draw the arrows on the speedometer before. I'm guessing that either way, the boxes should be filled in with the rest of the worksheets.
In the box that was on the worksheet, it said that d = 1/2gt^2, so from there, as Mr. Crane would put it, you have to plug and chug. You can round gravity to 10, and multiply it by 7 seconds squared, which is 49. My answer was 245 meters, too.
Yes Aliena you only have to know pukes (pic, knowns, unknowns, equation and solution) and know the formulas but he is going to let us use them in teh back of our notebook or give us them to write down. And for number three on page 7, I don't know if I'm right, but I think you just use that the oenny fell for 3 seconds and on the worksheet it says Distance= 5 x time^2 so you would do 5x3^2= 5x9= 45 so it was 45 meters long. that is just my guess though.
Yeah we will have too. I found the distance by using the formula they gave us. It was d=5t(squared). I plugged in 3 seconds and got the answer 45 meters.
for the boxes you just have to increase each odometer by 5 so the first one is 000 the next 005 the next 010... so on and for each the arrow just goes to the next number increasing by ten.
Is p.u.k.e.s always involved the square root formula? Does anyone know if that relates to every question? And depending on the picture the unknown can either be time or acceleration?? -Catherine Samara
Well, what equation you decide to use depends on the initial problem. Your unknown would be clarified in the question, and using the knowns you can derive from the problem, you would choose the equation that would fit it best. Does that answer your question?
Nazia is right about how it depends on the question and what you are looking for but all the other equations mainly sprout off of P=1/2at^2+Vot+Po. If you know how the other equations come off of that one then you are right Catherine.
It depends on what you need to find out. Nazia is right when she says that you can create your own formula, as loke as you take the varibles from a previous one and figure out how to move them to one side. Like if you want to find t in the equation V=at+Vo, then you would subtrat Vo from both sides, then divide by a. ~Makena
Definitely! You could always round your answers like he did in class, but it's always good to keep one around to double check your answers. Make sure you know how to properly insert the equations into it, though!
Mr. Crane gave me this practice problem today, and I have everything except the equation. If you guys could give me some insight on it, that would be great, and it's good practice for tomorrow's quiz! You're standing on the bleachers, which are 10 meters tall. You throw an object up at 20 m/s off the bleachers. How long is it in the air, and at what speed does it hit the ground?
for the test tomorrow if we need the formulas in our book, how many should we have and what should they be ? i missed a few classes and just wanna make sure i have all of the equations...
I have 4 equations... V= a x t + Starting V P= 1/2 a x t squared + Starting V + starting P p= v x t + starting P the square root of 2xchange in p/a = t
We started out with the statement that Michael Jordan has a hang time of 2 seconds. Then we had to find our own hang time. We measured how high we could jump, PUKED in our notebooks, and found our PERSONAL jumping velocity because it changes from person to person. Then we PUKED some more to find out if it is humanly possible to have a 2 second hang time. This was the lab as simply as I can say it. I can go into more detail if you need. -Kevin Meglathery
For ws pg.7, do want us to do P.U.K.E. for eace question(1-4)?
ReplyDeleteFor ws pg.8, are we completing the left side?
Finish both of the worksheets
DeleteNo you do not need to puke the whole WS. All the information and picture and equations are already given.
DeleteYou just have to answer the questions and finish both worksheets
ReplyDeleteFor page 8, does the time represent each notch? so if t=5 is the arrow at 5 notches?
ReplyDeleteFor the speedometer if t=5s then you speed would be 50m/s so your arrow would be pointing at the 5th dashed line(where it says 50)
DeleteYes thats what you are supposed to do, but isn't that what we did in class today?
DeleteI am not sure if thats what were supposed to do, but thats what i did on mine
ReplyDeleteFor #3 on page 7 how would you figure out the answer?

Delete@Mellisa you multiply 10*3(10 dollars per second) and then you add the $20 you already had
ReplyDeletewhoops, wrong #3
Delete@Melissa
you would use the first equation in the little bubble, so 10*3 gives you 30m/s
On page 8, are we answering the boxes under the speedometer?
ReplyDeleteyeah. you have to put in the speedometer as it goes up by 5 each time.
Delete-Skylar Young
Yes we are. We were supposed to do that as hw before though, but now would be a good time to do it.
ReplyDeleteWe were only supposed to draw the arrows on the speedometer before. I'm guessing that either way, the boxes should be filled in with the rest of the worksheets.
DeleteThanks that makes it much clearer.
Delete.
ReplyDeleteSo all we have to do is complete the worksheets? Nothing else, right?
ReplyDeleteYes, that's our only homework for tonight.
Deletewe don't have to complete the squirrell problem. right?
Delete-skylar Young
We might go over it in class tomorrow, but I think you should try to solve it using PUKES as practice for the quiz tomorrow.
DeleteHow do you do number 3 part 2 on ws pg. 8? Would you do 70 m/s times 7 seconds?
ReplyDeleteThis comment has been removed by the author.
Delete70/2•7 = 245 meters that is what I got.
Deletei just used the one on the paper. It was d=1/2g*t(squared)

DeleteI also got 245 meters.

For the test tomorrow do we just have to do P.U.K.E.S? Also, on page 7 how do you find the distance that the penny is falling in #3?
ReplyDeleteYes Aliena you only have to know pukes (pic, knowns, unknowns, equation and solution) and know the formulas but he is going to let us use them in teh back of our notebook or give us them to write down.

DeleteHe definitely wants us to have all formulas in the back of our notebooks because he might just let us use that instead of giving them to us
DeleteYeah we will have too. I found the distance by using the formula they gave us. It was d=5t(squared). I plugged in 3 seconds and got the answer 45 meters.
Deletethat is what I did Mimi. I got the same thing -Alexis Dearborn
DeleteI got 45 meters to. Good because I was worried about that one.
Delete~Makena
For the odometers, all that we do is half what is on the speedometer, and multiply by the time in seconds, no?
ReplyDeletefor the boxes you just have to increase each odometer by 5 so the first one is 000 the next 005 the next 010... so on and for each the arrow just goes to the next number increasing by ten.
ReplyDeleteAlexis i think you are talking about the speedometers. Noah you are right. You take half the m/s and multiply it by the time.
DeleteYeah I was thinking about the speedomters Mimi. Sorry. Noah this means you were right. Thanks for clearing that up Mimi!
DeleteIs p.u.k.e.s always involved the square root formula? Does anyone know if that relates to every question? And depending on the picture the unknown can either be time or acceleration??
ReplyDelete-Catherine Samara
what is the square root formula? the time one?
DeleteWell, what equation you decide to use depends on the initial problem. Your unknown would be clarified in the question, and using the knowns you can derive from the problem, you would choose the equation that would fit it best. Does that answer your question?
DeleteNazia is right about how it depends on the question and what you are looking for but all the other equations mainly sprout off of P=1/2at^2+Vot+Po. If you know how the other equations come off of that one then you are right Catherine.
DeleteIf you're going to derive your equations from that basic one, just be sure that you can use the right operations to solve for the designated variable.
DeleteIt depends on what you need to find out. Nazia is right when she says that you can create your own formula, as loke as you take the varibles from a previous one and figure out how to move them to one side.

Do you thik we should bring a calculator for this quiz tomorrow?
ReplyDeleteDefinitely! You could always round your answers like he did in class, but it's always good to keep one around to double check your answers. Make sure you know how to properly insert the equations into it, though!
DeleteDefinitely! It's always good to bring one just in case. Mr Crane will most likely want the exact answer.
DeleteThis post reminded me to bring my calculator. Good thing I did. Thanks Alexis!

Well you are looking for velocity and time. We have a bunch of formula for that so just plug them into on of them
DeleteGood thing you posted this Nazia! It helped me on the quiz.
