A merry-go-round is spinning at 1/2 revolution per second with eight kids hanging onto bars surrounding its periphery. The moment of inertia of the system is 5000 kg m². Four big kids pull themselves toward the center of the merry-go-round, changing the system moment of inertia to 4000 kg m2. What happens to the merry-go-round as a result of this action? O The merry go round speeds up to .625 revolutions per second. The merry go round slows down to 0.4 revolutions per second. O The merry go round speeds up to 1.0 revolutions per second. The meerry go round does not change speed, angular momentum cannot be changed.
