Question #23529

A clown pedals a unicycle applying an average torque of 7.50 Nm to its wheel. The wheel has a mass of 2.50 kg with an outside diameter of 0.600 m and an inside diameter of 0.525 m. The unicyclist and the unicycle have a combined mass of 90.0 kg. What is his translational and tangential acceleration? Be careful! Only the wheel's mass rotates but the total mass accelerates horizontally. [Answer: 0.285 m/s2]
