The drawing show three objects. They are connected by strings that pass over massless and friction-free pulley. The objects move, and the coefficient of kinetic friction between the middle object and the surface of the table is 0135. (a) What is the acceleration of the three objects? (b) Find the tension in the string attached to the 25.0 kg object. (c) Find the tension in the string attached to the 10.0 kg object.
