A wheel is rotating about an axis that is in the z-direction. The angular velocity ω_z is -6.00 rad/s at t = 0, increases linearly with time, and is +4.00 rad/s at t = 16.0 s. We have taken counterclockwise rotation to be 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?
