merry-go-round is being ridden by 2 children; one is 24.0 kg, and the other one is 15.0 kg as shown below. Both are sitting at the outside edge of a ring that has a mass of 57.0 kg and radius of 1.3 meters. The father gets them started by pushing at the outside edge with a tangential force of 268 Newtons through an angular distance of 102". a. In an ideal situation without friction from the bearing in the middle, what would be the angular speed of the ride after the force is removed? Angular Speed 4 rad/sec X Info Attempts: 22/00 b. If the final angular speed actually reached is 2.74 rad/sec, what is the frictional torque that exists in the ride? Torque from Friction 173 N-m X Info Attempts 1/00 Submit Submit c. Given this frictional torque, how many revolutions will the ride make before it comes to a stop after the father's force is removed? Angular Distance Revolutions into Attempts 0/00 Submit
