A 0.240 g pebble is fired at a speed of 14.6 m/s from the top of a 20.0 m tall building. Ignoring air resistance, find the kinetic energy with which the pebble strikes the ground when the pebble is fired vertically straight up. A ball which is thrown straight up takes 3.50 s to reach the maximum height. Determine the gravitational potential energy of the ball (m = 0.145 kg) when it reaches the maximum height.
