Problem

During the first

3\,\text{s}

of motion, a wheel’s angular position changes in such a way that its instantaneous angular velocity at

t=3\,\text{s}

is zero, yet its average angular velocity over the entire

0\text{–}3\,\text{s}

interval is not zero. In one or two sentences, explain how this situation is physically possible.
