60\,\text{g}

tennis ball is thrown vertically upward with a speed of

12\,\text{m\,s}^{-1}

. At the highest point of its flight it is struck straight downward so that it leaves the racket with a speed of

15\,\text{m\,s}^{-1}

downward. The contact time with the racket is

5.0\,\text{ms}

. Calculate the magnitude of the average force exerted on the ball.
