Question

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 ball after the collision.

Ferce as a Function of Time The figure above shows a graph of the force exerted by the tennis racquet on the bali as a function of time. Notice that the numbers and units are missing from the vertical axis, and the time on the horizontal axis is given in units of milliseconds The ball was not in contact with the raquet before the time , 5 0 ms or after the hme 25 0 ms Assume you can read the graph to an accuracy of at least two sigmficant figures. Calculate the maximum b) read the graph to an accuracy of at least two sigmficant figures. Calculate the matimum force that the racquet exerted on the ball

    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...

    please help! 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...
