A yo-yo (mass m, radius r ) is rolling down on a massless wire, which is fixed to the ceiling. Given: m = 0.10 kg, r = 0.04 m, IG = 1.2×10−4 kgm2, g = 9.81 m/s2 Determine the acceleration aG (in m/s2 ) of the center of gravity. MAD FBD Hint: When formulating a kinematic relationship think about the location of the ICoR.
