What is the angular acceleration of the disk and block

Reference no: EM13514610

A 4.0 kg block rests at the edge of a disk with a mass of 5.0 kg and a radius of 30 cm.

(a) A 2 N force is applied to the edge of the disk. What is the angular acceleration of the disk and block? (Hint: Don't forget to include the moment of inertia of the block. Treat it as a single particle).

(b) The block is held on the disk by static friction. The maximum force that static friction can oppose is 24 N. When the block comes off the disk, what is its tangential velocity?
