A merry-go-round is a common piece of playground equipment. A 3.0-m-diameter merry-go-round with a mass of 250 kg is spinning at 20 rpm. John runs tangent to the merry-go-round at 5.0 m/s, in the same direction that it is turning, and jumps onto the outer edge. John’s mass is 30 kg.

For the momentum says that the center his initial angular momentum is 05mr 05250kg15m 28125kgm 675kgm it makes the initial angular speed in rpm so ii the problem easier to have the law of angular speed in radians per second it makes the initial angular momentum is zero.
