A wheel with a rotational inertia of \( 0.50 \mathrm{~kg} \cdot \mathrm{m}^{2} \) about its central axis is initially rotating at an angular speed of \( 15 \mathrm{rad} / \mathrm{s} \). At time \( t=0 \), a man begins to slow it at a uniform rate until it stops at \( t=5.0 \mathrm{~s} \)
For the full \( 5.0 \mathrm{~s} \), at what average rate did the man do work?
