Problem

A wheel is rotating clockwise and slowing down in magnitude. Counterclockwise is defined as the positive direction. Which pair of signs for the wheel’s instantaneous angular velocity ω\omega and angular acceleration α\alpha is most consistent with this motion? a) ω>0,  α<0\omega>0,\;\alpha<0 b) ω<0,  α>0\omega<0,\;\alpha>0 c) ω<0,  α<0\omega<0,\;\alpha<0 d) ω>0,  α>0\omega>0,\;\alpha>0
