A girl of mass M stands on the rim of a frictionless merry-go-round of radius R and rotational inertia I that is not moving. She throws a rock of mass m horizontally in a direction that is tangent to the outer edge of the merry-go-round. The speed of the rock, relative to the ground, is ν. Afterward, what are (a) the angular speed of the merry-go-round and (b) the linear speed of the girl?
