A tennis ball has a mass of 58 g. A player hits the ball with a racket. The ball leaves the racket at 45 m/s.
Write the mass of the tennis ball in kilograms.
Calculate the momentum of the ball as it leaves the racket.
The player hits a second ball of the same mass. The second ball leaves the racket with half the momentum of the first ball. Calculate the velocity of the second ball.
