田 d) Imagine swinging a bat to hit the incoming baseball. It is known that a faster bat swing speed will result in a greater chance of a home run. Use the concepts of momentum, impulse, and collisions to explain why. Answer: B IU I e) If the speed of the bat before the hit is 33.5 m/s (~75 mph), what is the bat's speed after the hit in mph? (1 mph = 2.24 m/s) (Watch direction!)
