A uniform solid cylinder A of mass m1 can freely rotate about a horizontal axis fixed to a mount B of mass m2 (Fig. 1.66). A constant horizontal force F is applied to the end K of a light thread tightly wound on the cylinder. The friction between the mount and the supporting horizontal plane is assumed to be absent. Find: (a) the acceleration of the point K; (b) the kinetic energy of this system t seconds after the beginning of motion. |
