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 . We have taken counterclockwise rotation to be positive.
a. What is the angular displacement of the wheel from t = 0 s to t = 8.00 s ? express your answer in radians.
