A 250 kg rock falls off a cliff and comes to a rest on the ground, which is 40m below the cliff. At what point is the rock’s kinetic energy at maximum?
Answered by oobleck
just before it lands.

m g h + (1/2) m v^2 = constant
when h is minimum, v^2 is maximum

It is at its maximum kinetic energy when it is falling until it hits the ground which then it would be considered the maximum potential energy.
