I use the 1-d constant acceleration kinematics equations to determine the initi Use the kinematic equation for velocity, which is final velocity (v) equals initial velocity (u) plus acceleration (a) times time (t), or v = u + at. The ball is thrown straight up and will reach a maximum height, at which point its velocity will be zero, before beginning to fall downwards. Note that at the same distance below the point of release, the rock has the same velocity Now thinking about it the dropped ball starts at zero and ends up with some velocity whereas the thrown ball ends up with zero velocity because the distance, time and acceleration are the same (except the acceleration is negative for the thrown ball).
