Multiple Choice

A grinding wheel has a mass of $250 \mathrm{~kg}$ and moment of inertia of $500 \mathrm{~kg} \mathrm{~m}^{2}$ . A torque of $100 \mathrm{~N} \cdot \mathrm{m}$ is applied to the grinding wheel. If the wheel starts from rest, what is the angular momentum of the wheel after 5.0 seconds?

A) $650 \mathrm{~kg} \mathrm{~m}^{2} / \mathrm{s}$
B) $500 \mathrm{~kg} \mathrm{~m}^{2} / \mathrm{s}$
C) $250 \mathrm{~kg} \mathrm{~m}^{2} / \mathrm{s}$
D) $450 \mathrm{~kg} \mathrm{~m}^{2} / \mathrm{s}$
E) $300 \mathrm{~kg} \mathrm{~m}^{2} / \mathrm{s}$
