Athin-walled hoop of mass m and radius r starts from rest and rolls down an incline at an angle of θ. the static friction coefficient is assume the hoop rolls without slipping or bouncing. determine the acceleration of the center of mass, ag, and the angular acceleration α. be sure to draw a complete fbd. your answer should be in terms of the variables given in the problem statement. solve using: a. the moment equation about the mass center g. b. the moment equation about the contact point p. c. determine the frictional condition required for the hoop to roll without slipping. d. determine the equivalent mass of the system. e. determine the equivalent mass moment of inertia of the system
