10.5 Exercise 8

A hamster sits 0.10 m from the center of a lazy Susan of negligible mass. The wheel spins with a frequency of 1.0 rev/s. How will the frequency of the lazy Susan change if the hamster walks to 0.30 m from the center of rotation? Assume zero friction and no external torque.

1. It will speed up to 2.0 rev/s.
2. It will speed up to 9.0 rev/s.
3. It will slow to 0.11 rev/s.
4. It will slow to 0.22 rev/s.
