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.

A 2300 kg car moving at an initial speed of 25 m/s along a horizontal road skids to a stop in 50 m. (Note: When stopping without skidding and using conventional brakes, 100 percent of the kinetic energy is dissipated by friction within the brakes. With regenerative braking, such as that used in hybrid vehicles, only 70 percent of the kinetic energy is dissipated.)
