Assignment 6 Problems(Fall Term Physics 102) 2. A tennis player receives a shot with the ball (0.060 0 kg) traveling horizontally at 50.0 m/s and returns the shot with the ball traveling horizontally at 40.0 m/s in the opposite direction. (a) What is the impulse delivered to the ball by the racquet? (b) What work does the racquet do on the ball? I = 5.4 N-s towards the net, W = - 27.0 J 6. A stroboscopic photo of a club hitting a golf ball like that shown in Figure 6.3 of the text book was made by Harold Edgerton in 1933. The ball was initially at rest and the club was shown to be in contact with the club for about 0.0020 s. Also, the ball was found to end up with a speed of 2.0 x 10 2 ft/s. Assuming that the golf ball had a mass of 55 g, find the average force exerted by the club on the ball F av = 1.7 kN 33. A 12.0-g bullet is fired horizontally into a 100-g wooden block that is initially at rest on a frictionless horizontal surface and connected to a spring having spring constant 150 N/m. The bullet becomes embedded
