Problem

A solid disc starts with an angular velocity of

10\,\text{rad}\,\text{s}^{-1}

clockwise. It then experiences a constant angular acceleration of

3\,\text{rad}\,\text{s}^{-2}

anticlockwise for

8\,\text{s}

. Taking anticlockwise as the positive direction, determine the angular displacement of the disc during this interval. (a)

80\,\text{rad}

(b)

-16\,\text{rad}

(c)

16\,\text{rad}

(d)

-68\,\text{rad}
