What is its angular acceleration when the center is level

Reference no: EM13996710

A 5 kg uniform disk with a 40 cm radius swings without friction about a nail through a point 10 cm from the rim. It is released from rest from a position with its center above the nail.

(a) What is its angular velocity when the center is directly below the nail?

(b) What is its angular acceleration when the center is level with the nail?

(c) Suppose it hangs with its center directly below the nail. If it is pushed a small distance from this equilibrium position then what is its period of small oscillations?
