A 200g toy car is placed on a narrow 30cm radiustrack with wheel grooves that keep the car moving in acircle. The 1kg track is free to turn on a frictionlessvertical axis. The spokes have negligible mass. Afterthe cars switch is turned on, it slowly reaches a steadyspeed of 0.75m/s, relative to the track. What is thetracks angular velocity?
