Your pet hamster has an exercise wheel in his cage. He can climb into this wire wheel and then run in it as though he were on a treadmill. When he is running in the wheel, he remains stationary at the bottom of the wheel while it spins around him. In this case his angular velocity is
A. equal in magnitude to the wheel's angular velocity, but in the opposite direction.
B. zero.
C. increasing as he does work on the wheel.
D. equal in both size and direction to the angular velocity of the wheel.
