A light, flexible cable is wrapped around a solid cylinder with mass 3.3 kg and a radius of 0.8 meters. The cylinder rotates on a frictionless pin. The free end of the cable is tied to a 4.9 kg box that is initially 2.9 meters above the floor.
Determine the angular acceleration of the cylinder. (+ CCW)

Explanation:

We are given that

Mass,

Radius,r=0.8 m

Height,h=2.9 m

We have to find the angular acceleration of the cylinder.

According to question

Where

Substitute the value

Where
