Part A
A 210 g toy car is placed on a narrow 66-cm-diameter
track with wheel grooves that keep the car going in a
circle. The 1.1 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 0.73 m/s relative to the track. (Figure 1)
What then is the track's angular velocity, in rpm?
Express your answer to two significant figures and include the appropriate units.
