A strap, rod, or something comparable is used to spin up the disc. I imagine someone hand-starting a lawnmower. If he pulls the strap with a final speed before pulling the strap away, what is the rotation rate of the disk, w in rev/s? The moment of inertia of a disc is 1/2MR?. There's no sliding. Strap's final speed = v = 0.88 m/s. • The disc's radius is R = 0.7 m
