A merry-go-round spins freely when Diego moves quickly to the center along a radius of the merry-go-round. As he does this, it is true to say that Group of answer choices the rotational inertia of the system increases and the rotational speed decreases. the rotational inertia of the system decreases and the rotational speed increases. the rotational inertia of the system decreases and the rotational speed remains the same. the rotational inertia of the system increases and the rotational speed...

Suppose a child gets off a rotating merry-go-round. Does the angular velocity of the merry-go-round increase, decrease, or remain the same if: (a) He jumps off radially? (b) He jumps backward to land motionless? (c) He jumps straight up and hangs onto an overhead tree branch? (d) He jumps off forward, tangential to the edge?

Bubba (m=100kg) and Sally (m=60kg) are playing on a merry-go-round. Treat the merry-go-round as a disk with mass 100 kg and radius 1.3 m. Both Bubba and Salley are at the edge of the disk when the disk is rotating at .25 revolutions per second. Suppse Bubba moves inward so that he is now exactly at the center. Treat the two children as point masses. Assuming there is no external torques or forces, A) What is the new rotational speed...

A brave child decides to grab on to an already spinning merry-go-round. The child is initially at rest and has a mass of 31.5 kg. The child grabs and clings to a bar that is 1.40 m from the center of the merry-go-round, causing the angular velocity of the merry-go-round to abruptly drop from 55.0 rpm to 17.0 rpm. What is the moment of inertia of the merry-go-round with respect to its central axis?
