PhysicsQ&A LibraryTutorial Exercise A rotating wheel requires 13.0 s to rotate 43.0 revolutions. Its angular velocity at the end of the 13.0-s interval is 92.0 rad/s. What is the constant angular acceleration (in rad/s) of the wheel? Step 1 Converting to radians, we find that the angular displacement A0 undergone by the wheel in 43.0 revolutions is 2 T rad rev = 1 revStart your trial now! First week only $4.99!*arrow_forward*
