A uniform solid disk has a radius of r 052 m and mass of m, Ask an Expert

Academics

A uniform solid disk has a radius of R = 0.52 m and mass of M = 5.5 kg and is free to rotate about an axis through its center of mass. It is initially at rest, and at t = 0 a constant torque is applied such that the disk starts to turn with angular acceleration a = 18.8 rad/s2.

How many revolutions has the disk made at t = 8.2 seconds?
