Question

A ring of radius r is rotating about axis of ring such that angular velocity is given w=5t .Find acceleration of a point p on rim after 5 sec

Answer 1

The acceleration of the will remain same after 5 seconds.

Explanation:

• We know that the acceleration of the rotating particle is given by dω / dt.

• Therefore the acceleration of the rotation of body will be 5 m/s which is constant.

• Therefore after 5 seconds the acceleration of the body will not change
• It will remain same.
