How Does Friction Affect Acceleration and Tension in a 3-Block Pulley System?

[mike2148b]

1. The drawing shows three objects. They are connected by strings that pass over massless and friction free pulleys. The objects move, and the coefficient of kinetic friction between the middle object and the surface of the table is 0.100
(a) What is the Acceleration of the three objects? (b) Find the tension in each of the two strings.
