Hey guys. I might be out for a while. You need to really hunker down and read ch.3 2D motion.
Main Ideas
Time does not have direction
Therefor tx=ty
Set up all problems in x and y as separate problems. (you will be able to solve for time in one 1 of the directions)
Finally: the motion of the x does not affect the motion in the y. They are independant!
Check:
A bullet is dropped and a bullet is fired horizontally from the same height.
Which hits the ground first? If you said the one that is fired, reread the above, I you said the dropped one reread the above.
