Chapter 12, Problem 12.135(choose chapter or problem)
In FIGURE CP12.88, a 200 g toy car is placed on a narrow 60-cm-diameter track with wheel grooves that keep the car going in a circle. The 1.0 kg track is free to turn on a frictionless, vertical axis. The spokes have negligible mass. After the cars switch is turned on, it soon reaches a steady speed of 0.75 m/s relative to the track. What then is the tracks angular velocity, in rpm?
