A merry-go-round spends freely when diego moves quickly to the centre along a radius of the merry Go round as he does this it is true to say that the moment of the inertia of the system decreases and the angular speed increases it is so because of of the conservation of angular momentum.
Since angular momentum is the product of moment of inertia and angular speed thus as he moves towards the centre, the moment of inertia decreases and ultimately the angular speed needs to be increased so that the product of moment of inertia and angular speed remains constant to ensure the conservation of angular momentum.

A 70 kg merry-go-round disk has a radius of 3 meters and spins at 1.4 radians/sec with the 80 kg person on the edge. If the person moves so that they are now only 1 meter from the center, calculate the new angular speed of the merry-go-round system. Calculate the total kinetic energy of the system when the person is at the edge and when the person is at the 1 meter spot.

A disk-shaped merry-go-round of radius 2.63 m and mass 155 kg rotates freely with an angular speed of 0.692 rev/s. A 59.4 kg person running tangential to the rim of the merry-go-round at 3.27 m/s jumps onto its rim and holds on. Before jumping on the merry-go-round, the person was moving in the same direction as the merry-go-round's rim. (a) Does the kinetic energy of the system increase, decrease, or stay the same when the person jumps on the merry-go-round?...
