Question

A hamster sits 0.10 m from the center of a lazy Susan of negligible mass. The wheel has an angular velocity of 1.0 rev/s. How will the angular velocity 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.

a) It will speed up to 2.0 rev/s.

b) It will speed up to 9.0 rev/s.

c) It will slow to 0.01 rev/s.

d) It will slow to 0.02 rev/s.
