Problem 21PE

When serving a tennis ball, a player hits the ball when its velocity is zero (at the highest point of a vertical toss). The racquet exerts a force of 540 N on the ball for 5.00 ms, giving it a final velocity of 45.0 m/s. Using these data, find the mass of the ball.

Step-by-Step Solution:

Step-by-step solution In this problem a player hits a tennis ball which is initially at zero velocity ,now calculate the final velocity of the ball when a given amount of force is exerted on the ball. Step 1 of 3 When serving the tennis ball, the initial velocity is, The final velocity of tennis ball is: Therefore, the change in velocity of tennis ball is: Step 2 of 3 The force is expressed as, Here m is the mass, is the time of interaction, and is the change in velocity. The time of interaction of ball and racket is,
