A240 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 car's switch is turned on, it soon reaches a steady speed of 0.79 m/s relative to the track. what then is the track's angular velocity, in rpm?
