A wheel with a \( 0.10 \mathrm{~m} \) radius is rotating at \( 35 \mathrm{rev} / \mathrm{s} \). It then slows uniformly to \( 15 \mathrm{rev} / \mathrm{s} \) over a \( 3.0 \mathrm{~s} \) interval. What is the angular acceleration of a point on the wheel?
(A) \( -2.0 \mathrm{rev} / \mathrm{s}^{2} \)
(B) \( -6.7 \mathrm{rev} / \mathrm{s}^{2} \)
(C) \( -17 \mathrm{rev} / \mathrm{s}^{2} \)
(D) \( 0.67 \mathrm{rev} / \mathrm{s}^{2} \)
