A 10kg rock is pushed off the edge of a bridge 50 meters above the ground. What was the kinetic energy of the rock before it began to fall

Use Hooke's Law for this (F = - k s) : Where F is the spring's restoring force; k is the spring constant; and s is the stretch. The negative sign means the spring's restoring force is opposite the stretch direction.
