## Homework Statement

In the system shown in the figure , block A has mass = 2.00 , block B has mass = 0.360 , and the rope connecting them has a nonzero mass 0.240 . The rope has a total length 1.10 and the pulley has a very small radius. Let be the length of rope that hangs vertically between the pulley and block B. If there is friction between block A and the table top, with mu_Kinetic = 0.203 and mu_Static= 0.250, find the minimum value of the distance such that the blocks will start to move if they are initially at rest. Ignore any sag in the horizontal part of the rope.

## Homework Equations

F= ma

Torque = F*R

Work = F * ds

dx = Vot + .5at^2

Vf^2 = Vo^2 + 2ax

f = mu * N

## The Attempt at a Solution

The attempt at a solution

I know how to draw Free body diagram, but i got confused when the problem mentioned the mass of the pulley. What's the significance of it? Do I apply work in this? I literally no idea how to start this problem! >.<
