Question

A particle moves along a circular path of radius 20cm with a constant angular acceleration of 4
rad/s2 if the initial angular speed of the particle is 8 rad/s. Find an angular speed and angular
displacement of particle after 5 seconds.

Answer 1

Answer: 28 rad/s and zero.

Explanation:

So firstly, alpha (angular acceleration) = 4 rad/s^2

Omega knot (initial angular speed) = 8 rad/s

For time (t) = 5 sec

Omega (Final angular speed) = {8+(4x5)} = 28 rad/s

Angular displacement will be zero since it is going around a circle .
