A flywheel of radius

0.25\,\text{m}

starts from rest and reaches an angular velocity of

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

4\,\text{s}

with uniform angular acceleration. The linear distance travelled by a point on its rim during this time is closest to: (a)

8\,\text{m}

(b)

4\,\text{m}

(c)

2\,\text{m}

(d)

1\,\text{m}
