A 310 kg child runs with a speed of 300 ms tangential to


A 31.0 kg child runs with a speed of 3.00 m/s tangential to the rim of a stationary merry-go-round . The merry-go-round has a moment of inertia of 586 kg * m^2 and a radius of 2.51 m. When the child jumps onto the merry-go-round, the entire system begins to rotate.
