7. Refer to Conceptual Example 3 as an aid in understanding thisproblem. A hockey goalie is standing on ice. Another player fires a puck(m = 0.17 kg) at the goalie with a velocity of +65 m/s. (a) If the goaliecatches the puck with his glove in a time of 5.0 × 10-³ s, what is the averageforce (magnitude and direction) exerted on the goalie by the puck? (b) Insteadof catching the puck, the goalie slaps it with his stick and returns the puckstraight back to the player with a velocity of -65 m/s. The puck and stickare in contact for a time of 5.0 × 10-3 s. Now what is the average forceexerted on the goalie by the puck? Verify that your answers to parts (a)and (b) are consistent with the conclusion of Conceptual Example 3.

On the set of a new Hollywood movie, a 74.1-kg stunt actor (Max Payne) is tossed straight out of a helicopter hovering (stationary) at a height of 43.4 meters. The stunt actor is thrown from the helicopter at a speed of 4.17 m/s, eventually landing in the water below. Determine the stunt actor's impact speed and assume negligible air resistance. You can use the approximation that g = 10 m/s2.
