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 1/2MR2. There's no sliding. • Strap's final speed = v = 1.05 m/s. • The disc's radius is R = 0.6 m • The small disc's radius is 1 cm • The disc's mass is M = 0.7 kg %3D

A strap, rod, or something comparable is used to spin up the disc. T 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 = 0.74 m/s. • The disc's radius is R = 0.7 m • The small disc's radius is 1 cm • The disc's mass is M = 0.7 kg
