The mass of a regulation tennis ball is 57 g (although it can vary slightly), and tests have hown that the ball is in contact with the tennis racket for 30 ms. (This number can also ary, depending on the racket and swing.) We shall assume a 30.0 ms contact time. One of the fastest-known served tennis balls was served by "Big Bill" Tilden in 1931, and its peed was measured to be 73 m/s. Suppose that the positive direction of the z-axis is along the direction of motion of the ball after Big Bill's hit.

  • What is the x-component of the impulse exerted by Big Bill on the tennis ball in his record serve? Assume that the initial speed of the ball is zero.
  • If Big Bill's opponent returned his serve with a speed of 55 m/s, what is the x-component of the impulse he exerted on the ball, assuming only horizontal motion?

- What is the *x*-component of the impulse exerted by Big Bill on the tennis ball in his record serve? Assume that the initial speed of the ball is zero. - If Big Bill's opponent returned his serve with a speed of 55 m/s, what is the *x*-component of the impulse he exerted on the ball, assuming only horizontal motion?
