According to studies by Stevenson (1985), a diver (mass = 58 kg) entering the water from a 10 m tower has a vertical velccity of 16.8 m/s downward at the instant that they first touch the water. At an instant 0.133 s later, the velocity of the diver has decreased to 5.2 m/s downward. a. What was the change in the linear momentum of the diver over the 0.133 s interval after contact with the water? b. What was the average net impulse exerted on the diver over the 0.133 s interval after contact with the water? c. What was the average net force exerted on the diver during the 0.133 s interval after contact with the water? d. Draw a free-body diagram of the diver at t-0.100 s. e. What was the average acceleration of the diver during the initial 0.133 s interval after contact with the water?

An overhead view of part of a pinball game is shown. If the plunger imparts an initial speed of 2.9 m/s to the ball at time t = 0, determine the acceleration a of the ball (a) at time t = 0.08 s and (b) at time t = 0.19 s. At point F, the speed of the pinball has decreased by 12% from the initial value, and this decrease may be assumed to occur uniformly over the total distance traveled by the pinball.
