Walking on a Spinning Disk#

A \({{params_m}}\ \rm{kg}\) man is walking at a constant speed towards the center of a platform spinning at a constant rate of \({{params.theta_dot}} \ \rm{rad/s}\).

A disk with a mass at distance r1 from the center. The mass moves closer to the center, where the radius is r2.

Part 1#

If his initial distance from the center is \(r_1={{params_r1}} \ \rm{m}\), and he moves to a new location where \(r={{params_r2}}\ \rm{m}\), how much work did he do?
