An object at rest begins to rotate with a constant angular acceleration.

If the angular speed of the object is ω after the time t, what was its angular speed at the time t/2?


Expert Answer

Step 1

Angular acceleration is,

Step 2

It is given that the angular acceleration is constant. So, in order to angular acceleration become constant, as times decreases by half the initial value, change in angular velocity must also decreases by two times the initial value.

Step 3

2 t/2
