A boy of mass 35.2 kg is standing on the edge of a merry-go-round which is at rest.
A boy of mass 35.2 kg is standing on the edge of a merry-go-round which is at rest. The merry-go-round is a flat disk of mass 59.3 kg and radius 2.3m (the moment of inertia of a cylinder is ½ mr^2 ), turning on a frictionless pivot. The boy starts to walk around the edge of the merry-go-round in the clock-wise direction (when viewed from the top). When the boy is moving at 2.4 m/s relative to the merry-go-round: a....

Starting at rest, a child applies a 63N force tangent to the
edge of a merry-go-round through 31 2 rotations. At that moment,
she stops and admires her spinning merry-go-round. Then she jumps
onto the edge of the merry-go-round. The girl’s mass is 25kg, the
merry-go-round’s moment of inertia is 70kg· m2, and the
merrygo-round’s diameter is 2.0m. What is the final angular speed of
the girl and merry-go-round?
