Question

Consider the video of the kids on the merry-go-round with the leaf blower. Let’s assume that the leaf blower creates 15 ft-lb of torque on the system. Assume there are four children of equal masses on the merry-go-round and that they are equally spaced. The radius is 5 ft. The system starts at rest and then reaches a terminal velocity of 7 ft/sec in 20 seconds. Determine how much each child weighs (in lb).

This question has to do with angular momentum and multi-particle systems
