A ball having a mass of 2 kilograms, starting at ground level, is shot straight up into the air. It reaches a height of 10 meters and falls back down to the ground. What is the ball's Kinetic Energy just as it is shot up into the air? What is the ball's Kinetic Energy at the top of its flight? What is the ball's Kinetic Energy as it hits the ground? What is the ball's Total Energy at these same three points in its flight?
