Asked by CHELsea
Ball is thrown vertically upward with a speed of 25.0 m/s. What is it's velocity when it returns to the level from which it had started ?
After computations: The ball reaches its highest pt at 32.4 meters.
It takes the ball 2.55sec to reach its highest pt.
It take the ball 2.55 sec to hit ground after it reaches its highest point
so what is its velocity ?

Use
v=u+at
where a=-9.8,
and
u=0 (at the highest point)
You could have arrived at the same conclusion by considerations of kinetic energy.
