Projectile Notes
Projectile problems 30,37,53,90 use the previous info from class with launch angles given.
Please can Simone post the given information from class
dyi=from notes
Vo=from notes
Looking for the range.
These problems involve a lot of info so you MUST Use pukes to solve...
Separate into to problems one in the x and one in the y.
Time is the only factor that can be shared between the two. All the other variables are like your toothbrush not everyone get to use it.
dyo = 1.15 meters
ReplyDeleteVxo= 4.65 m/s
i believe
i'm not sure if this has my name attached so its Martin Brenner
i wasnt here last class so will i be able to do it?- danielle
ReplyDeleteWhere are the problems?
ReplyDeletei can't find the problems i checked the textbook and the online study guide can we get more time and a page number please!?
ReplyDeleteare these problems in the textbook?
ReplyDeletedid anyone find where these question were? and i am lost on the triangle problem from last week. . . jade maccini
ReplyDeleteAfter doing the homework, and myself I thought I understood it very well, but I found this video and it was just someone else explaining a question that we are working on. It is beneficial to just hear the same thing from two different people, and which a lot of the times can help if anyone is not getting it 100%! -Mary Frances Wenig

where do we find the questions? and for the equations to find the solutions we use the original one in class with the acceleration, time velocity and inital distance correct??
ReplyDeleteFor the problems we have for homework, we are just using the same information that we set up the lab with including the one we did in class at 30 degrees so you can use all that information just change that angle you are firing the object at.
ReplyDeleteHow exactly would the equation at a 90 degree angle work? Since it would fire straight up, what are we looking for and how can we find it? I'm assuming the position in the x is always o and y changes... - Matthew Johnson
ReplyDeletewhat are we solving for for the 90 degree angle? we can't solve for dx because it doesn't move in the x at all. so are we just finding time?
ReplyDeleteDoes anyone understand how to do the 90 degree angle one?
