Find what time is required for change in angular velocity

Assignment Help Physics
Reference no: EM13670934

A spinning wheel on a fireworks display is initially rotating in a counterclockwise direction. The wheel has an angular acceleration of -3.20 rad/s2. Because of this acceleration, the angular velocity of the wheel changes from its initial value to a final value of -28.0 rad/s. While this change occurs, the angular displacement of the wheel is zero. (Note the similarity to that of a ball being thrown vertically upward, coming to a momentary halt, and then falling downward to its initial position.) Find what time is required for the change in the angular velocity to occur.
