A flywheel rotates at a constant angular acceleration. At time t = 1.38 s, it rotates with a speed of ω = 2.40 rad/s

in the clockwise direction. At time t = 5.97 s, it rotates with a speed of ω = 2.40 rad/s in the counter-clockwise
direction. What is its angular displacement from t = 0.00 s to t = 7.00 s? What is the tangential acceleration of apoint on the flywheel 0.223 m from the axis?
