Problem: A wheel with a mass of 10 kg and a radius or 0.72 m spins at a rate of 180 revolutions per minute.
Required:
Question 1: What is the translational speed of a point on the edge of the wheel (in meters per second)?
Question 2: If the wheel slows to a stop in 19s, what is the average angular acceleration of the wheel during that time?
