Physics
A girl stands on the rim of a merry-go-round of radius 2.0 mthat is not moving. The rotational inertia of the merry-go-round(including the girl’s inertia) is 800 kg∙m2. She throws a rock ofmass 0.5 kg horizontally in a direction that is tangent to theouter edge of the merry-go-round. The speed of the rock, relativeto the ground, is 4.0 m/s. (a) What is the angular speed of themerry-go-round? (b) What is the speed of the girl?
