All I really need help with is finding out how to solve it.

I'm assuming the the ball goes vertically upwards
use one of the equations for constant acceleration
initial velocity u = 25 ft/s
final velocity v  ( at maxm height) = 0 ft/s
acceleration a due to gravity = -32 ft/s^2 ( negative because motion is against gravity)

height s is to be found

welshfella · Answer

v^2 = u^2 + 2as
0 = 25^2 - 2*32* s

solve for s
