A light rope is attached to a block with mass M1 = 3 kg that rests on [1.] a horizontal surface with coefficient of friction µk = 0.2. The horizontal rope passes over a frictionless, massless pulley, and a block of mass M2 = 7 kg is suspended from the other end. (a.) What is acceleration of the blocks? (b.) What is the tension in the rope? (c.) If the coefficient of static friction µs : 0.45, what is the smallest M, which is needed to set the masses in motion? M1 M2
