Question

The angular velocity of the particle is given by = 2t^3 − 6t
^2 + 3.

Find the time when its angular acceleration becomes zero. ​

Answer 1

Just differentiate the angular velocity and u will get angular acceleration....

So ang.acceleration a = 6t^2-12t

0= 6t^2 - 12t

t = 2 sec

Answer 2

Answer:t=1s
