The mass of a regulation tennis ball is 57 g (although it can vary slightly), and tests have shown that the ball is in contact with the tennis racket for 30 ms. (This number can also vary, 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 speed was measured to be 73 m/s. Suppose that the positive direction of the x-axis is along the direction of motion of the ball after Big Bill's hit.
a.) 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
c.)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?

A tennis ball of mass 0.0600 kg is initially moving horizontally with a speed of 25.0 m/s. A tennis player hits it with his racket with an average force of 66 N, sending the ball back in the opposite direction with a speed of 35.0 m/s. For how much time was the racket and ball in contact, in units of seconds?

a tennis ball was hit with a tennis racquet. The ball was hit in
the same direction from which it approached the raquet ( the
opposite of the direction it was going), so it was s essentially a
one- dimensional collision. The 60.0 gram tennis ball approached
the racquet with a speed of 34.3 m/s. The tennis racquet gave the
ball an impulse of 4.5 newton-seconds. a) Find the velocity of the

A racquetball of mass m = 42.9 g, initially moving at 35.0 m/s horizontally in the positive x direction, is struck by a racket. After being struck, the ball moves back in the opposite direction at an angle of 35.0° above the horizontal with a speed of 62.0 m/s. What is the average vector force exerted on the racket by the ball if they are in contact for 2.60 ms? (Assume the positive y direction is vertically upward. Express your...

The figure below shows a metal ball with a mass of 2.84 kg bouncing off a wall. The ball has the same speed just before and just after the impact (v - 10.0 ms, and the angle its path makes with the wall is 8 - 60.0° as shown. (Because we are analyzing the motion of the ball over a very short time just before and after Impact, you may safely ignore the effect of gravity on the...
