The angle through which a rotating wheel has turned in time is given by = , where is in radians and in seconds. Determine an expression for the instantaneous angular velocity if is in seconds. Determine an expression for the instantaneous angular acceleration if is in seconds. If = 8.0 , = 13.0 , = 1.5 , evaluate at = 3.2 . Evaluate at = 3.2 . What is the average angular velocity between = 2.0 and =3.2 ? What is the average angular acceleration between = 2.0 and =3.2?
