Answer to Question #226631 in Mechanical Engineering for Papi Chulo

Question #226631

A 320 mm diameter-grinding wheel must be driven at a peripheral grinding speed of 1200 meters/min. It takes 62 seconds to reach this speed from rest, runs at this speed for the following two and a half minutes and then begins to decelerate uniformly, coming to rest after a further 10 seconds. Draw a neat angular velocity/time graph and use it to determine how many revolutions the wheel made since starting from rest.
