22 Questions for Chapter 2: Motion in One Dimension

  1. On another planet, a marble is released from rest at the top of a high cliff. It falls4.00m in the first 1 s of its motion. Through what additional distance does it fall in the next 1s ? (a) 4.00m (b)8.00 m (c) 12.0 m (d) 16.0m (e) 20.0m

  3. A car travels along a straight line at a constant speed of 60.0 mi/h for a distance d and then another distance d in the same direction at another constant speed. The average velocity for the entire trip is 30.0 mi/h.

  5. Each of the strobe photographs (a), (b), and (c) in Figure OQ2.18 was taken of a single disk moving toward the right, which we take as the positive direction. Within each photograph, the time interval between images is constant.

  6. Try the following experiment away from traffic where you can do it safely. With the car you are driving moving slowly on a straight, level road, shift the transmission into neutral and let the car coast. At the moment the car comes to a complete stop, step hard on the brake and notice what you feel. Now repeat the same experiment on a fairly gentle, uphill slope. Explain the difference in what a person riding in the car feels in the two cases. (Brian Popp suggested the idea for this question.)
