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

A small child of mass mc is sitting on the edge of a large merry-go-round which is initially at rest. For simplicity, assume the merry-go-round is a uniform disk of mass mm and radius R. An ice-cream truck drives by and in a moment of benevolence, the driver hurls a huge scoop of vanilla ice cream at the child. The scoop has mass ms and is traveling parallel to the ground and tangent to the merry-go-round at a speed of...

A disc-shaped merry-go-round has a mass of 100 kg and a radius of 1.60 m and is initially spinning at 20.0 rpm, with a 33-kg child sitting at its center. The child then walks out to the edge of the disc. (a) Find the initial and final moments of inertia of the system (disc + child), treating the child as a point particle. (b) State why the system’s angular momentum is conserved. (You can assume that the axis of the...

A large turntable (a merry-go-round) is able to rotate with friction about a fixed vertical axis through its center. The moment of inertia of the turntable about this axis is 1300  kg⋅m2 . A daring child, with a mass of 40.0  kg , is riding the merry-go-round while wearing roller skates. She is initially standing at the center of the turntable (and spinning with the turntable); at this time, the turntable is making one revolution every 6.50  seconds . The adventurous child finds...
