    Rotational Kinemaitcs
    A rotating wheel accelerates uniformly at 6.2 rad/s, and completes 25 revolutions during a 5.0 s interval.
    (a) What is the angular velocity of the wheel
    At the start of the 5.0 s interval?
    (b) What is the angular velocity of the wheel at
    The end of the 5.0 s interval?
