A merry-go-round has a radius of 17.9 m and a moment of inertia of 390 kg-m². A boy of mass 44.5 kg runs tangent to the rim at a speed of 2.87 m/s and jumps on. If the merry-go-round is initially at rest, what is the angular velocity after the boy jumps on? Help on how to format answers: units wy= Submit answer
