Kinematics Multiples
... The KE is a max. when the ball impacts the floor and then decreases—which rules out graphs C and E. Although the speed varies linearly with time, KE is the square of the speed, so it should be a parabola, which rules out graph B. In graph D the PE is decreasing quickly at first and then more slowly ...
