82. (a) Using Eq. 2-16 for the translational (center-of-mass) motion, we find vv a xa v x 2 0 2 0 2 2 2 =+ ¡ =− Δ Δ which yields a = –4.11 for v 0 = 43 and Δ x = 225 (SI units understood). The magnitude of the linear acceleration of the center of mass is therefore 4.11 m/s 2 . (b) With R = 0.250 m, Eq. 11-6 gives 2 | | / 16.4rad/s . aR α == If the wheel is going rightward, it is rotating in a clockwise sense. Since it is slowing
