Aball is dropped from the top of a cliff. by the time it reaches the ground, all the energy in its gravitational potential energy store has been transferred into its kinetic energy store. if the ball is travelling at 20 m/s when it hits the ground, what height was it dropped from? (assume that the gravitational field strength is 10 n/kg.)
