Two children (m = 33.0 kg each) stand opposite each other on the edge of a merry-go-round. The merry-go-round, which has a mass of 1.78 ✕ 102 kg and a radius of 1.4 m, is spinning at a constant rate of 0.42 rev/s. Treat the two children and the merry-go-round as a system.
(a) Calculate the angular momentum of the system, treating each
child as a particle. (Give the magnitude.)
(b) Calculate the total kinetic energy of the system.
(c) Both children walk half the distance toward the center of
the merry-go-round. Calculate the final angular speed of the
system.
