Simple throwing ball "up" problem
Ball is thrown vertically with upward velocity of 18m/s when it reaches 1/4 of its maximum height above its launch point. Find initial launch velocity of ball.
0.5mv2, mgh, v=d/t
The 1/4 of the maximum height is throwing me off.
I tried using kinematics equations to first solve for the first part of the throw (the 1/4)
and then use final velocity of zero at the max height using deceleration of gravity to find this height.
I'm stumped, any help is appreciated.
Thanks.
