A tennis ball of mass 0.0621 kg is served. It strikes the ground with a velocity of 54.0 m/s (120 mi/h) at an angle of 22.0 degrees below the horizontal. Just after the bounce it is moving at 53.0 m/s at an angle of 18.0 degrees above the horizontal. If the interaction with the ground lasts 0.0630 s, what is the magnitude of the average force exerted by the ground on the ball ?
