Chapter 9, Problem 96PP

You’re interested in the intersection of physics and sports, and you recognize that many sporting events involve collisions—bat and baseball, foot and football, hockey stick and puck, basketball and floor. Using strobe photography, you embark on a study of such collisions. Figure 9.31 is your strobe photo of a ball bouncing off the floor. The ball is launched from a point near the top left of the photo and your camera then captures it undergoing three subsequent collisions with the floor.

FIGURE 9.31 Passage Problems 94-97

The component of the ball’s velocity whose magnitude affected by the collisions is

1. a. horizontal.
2. b. vertical.
3. c. Both are affected equally.
