For a top player, a tennis ball may leave the racket on the serve with a speed of 55 m/s (about 120 mi/h). If the ball has a mass of 0.060 kg and is in contact with the racket for about 4 ms (4 x 10-3 s), estimate the average force on the ball. Would this force be large enough to lift a 60-kg person?

Roger is a tennis player, he performs a serve with a 0.68 kg
tennis racket. The serve took 0.4 s from the back of the swing
until ball impact. The angular velocity of the racket at the start
of the serve is zero, and it reaches a peak value equal to 29
rad.s-1 at the instant of ball impact. The
peak linear velocity of the racket at the center of gravity is
equal to 13.6 m.s-1.

As a tennis ball is struck, it departs from the racket
horizontally with a speed of 29.0 m/s. The ball hits the court at a
horizontal distance of 20.3 m from the racket. How far above the
court is the tennis ball when it leaves the racket?

a) The probability
of the first serve is good for a tennis player is denoted by p. A
player decides to increase p by taking a training program. After
the training program completed, the player wishes to test Ho : p =
0.40 against HI : p > 0.40 . Let y be the number of first serve
is good. Given that the total number of first serve, n = 20 and the
critical region of the test is y...

If the probability that a certain tennis player will serve an
ace is 1/ 6 , what is the probability that he will serve exactly
four aces out of six serves? (Assume that the six serves are
independent. Round your answer to four decimal places.)
