The 29-kg wheel is rolling under the constant moment of M = 85 N·m. The wheel has
radius r = 0.57 m, has mass center at point G, and the radius of gyration is kg = 0.25
m. The coefficients of friction between the wheel and the ground is g = 0.37 and
μk = 0.16. If the wheel rolls while slipping, determine the magnitude of the linear
acceleration of point G (in m/s²). Please pay attention: the numbers may change
since they are randomized. Your answer must include 2 places after the decimal
point. Take g = 9.81 m/s².
