Problem

A potter’s wheel has a rotational inertia of

2.5\,\text{kg}\,\text{m}^2

. Starting from rest, it must reach an angular speed of

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

5.0\,\text{s}

. What constant net torque must be applied? a)

1.6\,\text{N}\,\text{m}

2.5\,\text{N}\,\text{m}

4.0\,\text{N}\,\text{m}

8.0\,\text{N}\,\text{m}
