1. A man with mass m walks with a constant velocity v with respect to the ground on the edge of a marry-go-round that has a radius of R and moment of inertia I. The system starts from rest.
a) what is the angular velocity of the marry-go-round?
b) when the man completes a full cycle (returns to its initial position) at what angle did the marry-go-round rotate?
c)what is the friction coefficient between the man and the marry-go-round for the man not to get off the marry-go-round?
2. No relevant equations.
3. I tried to use conservation of angular momentum and got this:
I[tex]\omega[/tex]+mR2v/R=0
