A wheel is rotating about an axis that is in the z-direction. The angular velocity ωz is -6.00 rad/s at t = 0, increases linearly with time, and is +4.00 rad/s at t = 16.0 s. Counterclockwise rotation is taken as positive.
(a) Is the angular acceleration during this time interval positive or negative?
(b) How long is the time interval during which the speed of the wheel is increasing?
(c) How long is the time interval during which the speed of the wheel is decreasing?
(d) What is the angular displacement of the wheel from t = 0 s to t = 16.0 s?
