The 0.4m radius disk starts from rest at an angular acceleration of t ^ (1/2) rads / s ^ 2 ccw, where t is in seconds. determines the angular velocity it reaches in rads / s at a point on its circumference, when 2 seconds have passed. Enter units and direction

Homework Answers

Answer #1

The angular velocity after 2 seconds will be 0.35 rad/s ccw.

The angular velocity will be same for a point on the circumference or any other internal point. The tangential (linear) velocity increases as we move from the centre to the circumference.

The detailed solution is attached in the image.
