12-15 A light string is wrapped around a solid cylinder that has a radius R = 5 cm and a mass M = 12 kg. The cylinder is on a plane with an inclination angle of 32°. The free end of the string passes over an inertialess and frictionless pulley to a block with mass m = 2 kg as in the diagram at right. Find the linear acceleration of the cylinder and of the hang- ing block. [Hint: What is the relationship between the linear acceleration of the cylinder and that of the block?] M= 12 Kg R=5cm m= 2 kg 32° Problem 12-15
