A wheel rotates about a fixed axis with an initial angular velocity of 20 rad/s. During a 5.0-s interval the angular velocity increases to 40 rad/s. Assume that
the angular acceleration was constant during the 5.0-s interval. How many
revolutions does the wheel turn through during the 5.0-s interval?
