19. (Rolling, Torque, and Angular Moment um) A hollow cylinder of outer radius R = 5 the center of mass Icom = MR starts from rest and moves down an incline tilted at an angle 0 = 20° from the horizontal. The center of mass of the cylinder has dropped a vertical distance h = 30 cm when it reaches the bottom of the incline. The coefficient of static friction cm and mass M = 50 g with moment of inertia about between the cylinder and the surface is µ.. The cylinder rolls without slipping down the incline. Answer: i) p, > 0.18 ii) v= 1.7 m/s i What is the minimum value for the coef- ficient of static friction u, such that the cylinder rolls without slipping down the incline plane? ii What is the magnitude of the velocity of the center of nass of the cylinder when it reaches the bottom of the incline? 19.
