The drawing shows three objects. They are connected by stringsthat pass over massless and friction-free pulleys. The objectsmove, and the coefficient of kinetic friction between the middleobject and the surface of the table is 0.144. (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 the10.0 kg object.
