The 10-kg wheel is rolling under the constant moment of M = 97 N-m. The wheel has radius r= 0.59 m, has mass center at point G, and the radius of gyration is kg = 0.27 m. The coefficients of friction between the wheel and the ground is ls = 0.25 and Hk = 0.14. 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/s?. M G

Maya's team has designed a wheelchair for elderly, which has a wheel with a mass of 25 kg and a radius of gyration kß = 0.15 m. The wheel is initially spinning at w = 40 rad/s. The task is to determine the time required for the wheel's motion to come to a stop after being placed on the ground, considering the coefficient of kinetic friction µc =0.5 and assuming that there are no additional weights on the wheelchair themselves. Additionally, the students must calculate the horizontal and vertical components of the reaction that the pin at point A exerts on AB during this time. Neglect the mass of AB.
