10.6 Exercise 2

Avg difficulty 2.5

A box with a mass of 2.0 kg rests on one end of a seesaw. The seesaw is 6.0 m long, and we can assume it has negligible mass. Approximately what angular momentum will the box have if someone with a mass of 65 kg sits on the other end of the seesaw quickly, with a velocity of 1.2 m/s?

  1. 702 kg•m2/s
  2. 39 kg•m2/s
  3. 18 kg•m2/s
  4. 1.2 kg•m2/s
