Question 1 (6/79) The 10-kg wheel with a radius of gyration of 180 mm about its centre O is released from rest on the 60 degree incline and slips as it rolls. If the kinetic coefficient of friction is uk 0.30, calculate the acceleration ao of the centre O of the wheel and its angular acceleration. (Ans: 7.02 m/s², 9.08 rad/s2). 200 mm 60° Fig 1 H=0.30
