A merry-go-round is a common piece of playground equipment. A 3.0-mm-diameter merry-go-round, which can be modeled as a disk with a mass of 260 kgkg , is spinning at 17 rpmrpm. John runs tangent to the merry-go-round at 5.4 m/sm/s, in the same direction that it is turning, and jumps onto the outer edge. John's mass is 30 kgkg.     Part A What is the merry-go-round's angular velocity, in rpmrpm, after John jumps on? Express your answer in revolutions per minute.
