3) John Isner holds the official ATP record for fastest serve at 157 mph. Mr. Isner is 6 feet 10 inches tall, and we can assume that the length of his arm is roughly half his height. He uses a racquet 27 inches long. A tennis court is 60 feet long from baseline to service line, and the net is 3 feet high in the center. Assume Mr. Isner hits the service line with a serve up the T. Calculate the acceleration imparted to the ball at the moment of impact on his serve. Assume an inelastic collision (that is, the flex of the racquet and strings do not contribute to the acceleration) and that the serve is flat (no spin). b. At what angle will the ball impact the court? C. Suppose you are waiting to return Mr. Isner's serve. You're standing on the baseline 78 feet opposite Mr. Isner. Assume that the serve hits the service line and rebounds at the same angle as that calculated in (b). How much time will you have to react to the serve? а.

3) John Isner holds the official ATP record for fastest serve at 157 mph. Mr. Isner is 6 feet 10 inches tall, and we can assume that the length of his arm is roughly half his height. He uses a racquet 27 inches long. A tennis court is 60 feet long from baseline to service line, and the net is 3 feet high in the center. Assume Mr. Isner hits the service line with a serve up the T. a. Calculate the acceleration imparted to the ball at the moment of impact on his serve. Assume an inelastic collision (that is, the flex of the racquet and strings do not contribute to the acceleration) and that the serve is flat (no spin). b. At what angle will the ball impact the court? C. Suppose you are waiting to return Mr. Isner’s serve. You're standing on the baseline 78 feet opposite Mr. Isner. Assume that the serve hits the service line and rebounds at the same angle as that calculated in (b). How much time will you have to react to the serve?
