Here is your answer Hope This Answer Helps You

Angular speed (ω) =10 rad/s

Wanted :

(a) Angular speed (ω) after 10 seconds.

(b) Angle (θ) after 10 seconds

Solution :

(a) Angular speed (ω) after 10 seconds

Object in uniform circular motion so that angular speed is constant, 10 rad/s.

(b) Angular displacement (θ)

Constant angular speed 10 radians/second means the object around 10 radians each second. After 10 seconds, the object around 10 x 10 radians = 100 radians.
