Problem

A wheel initially spins clockwise at 8 rad s−18\,\text{rad}\,\text{s}^{-1}. Treating clockwise directions as negative, it is subjected to a constant angular acceleration of +2 rad s−2+2\,\text{rad}\,\text{s}^{-2} (anticlockwise) for 3 s3\,\text{s}. In one or two sentences explain whether the magnitude of its angular velocity will increase, decrease or become zero after this interval and why.
