Homework Statement
At the top of the building that's 65m high, a guy throws a ball upward.
The ball comes back down and hits the ground in 4 seconds.
A)What is the initial velocity when the guy threw the ball?
B)What is the highest height of the ball?
C)At what time does the ball comes back to him?I'm just stumped how the hell I can start off even...
There was a homework problem very similar to this but it gave initial velocity..this problem doesn't and I don't know how to start...
Any advice would be fantastic..
(This was my first physics quiz...is it even possible to solve this?!?)
Please help...
