Problem 12: A merry-go-round is a playground ride that consists of a large disk mounted to that it can freely rotate in a horizontal plane. The merry-go-round shown is initially at rest, has a radius R = 13 meters, and a mass M = 241 kg. A small boy of mass m = 46 kg runs tangentially to the merry-go-round at a speed of v = 1.8 m/s, and jumps on. Randomized Variables R = 13 meters M=241 kg m = 46 kg v = 1.8 m/s

Question
Problem 12: A merry-go-round is a playground ride that consists of a large disk mounted to
that it can freely rotate in a horizontal plane. The merry-go-round shown is initially at rest, has a
radius R = 1.3 meters, and a mass M = 241 kg. A small boy of mass m = 46 kg runs tangentially to
the merry-go-round at a speed of v = 1.8 m/s, and jumps on.
Randomized Variables
R = 1.3 meters
M = 241 kg
m = 46 kg
v = 1.8 m/s
