A tennis ball hits a racket with a velocity of 25 m s-1, and leaves the racket travelling with a velocity of 15 m s-1 in the opposite direction. The ball is in contact with the racket for 0.05 s.
What is the magnitude of the average acceleration of the ball whilst it is in contact with the racket?
200 m s−2200\text{ m s}^{-2}200 m s−2
400 m s−2400\text{ m s}^{-2}400 m s−2
800 m s−2800\text{ m s}^{-2}800 m s−2
1000 m s−21000\text{ m s}^{-2}1000 m s−2
