3. A bunch of high school juniors were playing on the merry go round on the local elementary playground on a recent Saturday morning. They got the merry go round going really fast and then jumped off and started walking away, leaving the 150 kg merry go round spinning. The 150 kg mass of the merry go round represents a moment of inertia of 2,354 N m. You suddenly notice a 3 year old running to the spinning merry go round. You panic and start running to the 3 year old to rescue them before they get knocked down by the merry go round and badly injured. Assume the mass of the merry go round is all on the edge, not the center. What is the diameter of the merry go round? What amount of torque would you need to apply to put the merry go round safely in equilibrium so other children do not get hurt? What amount of force would be required to create that torque
