## Homework Statement

A block of mass 2.42kg is accelerated across a rough surface by a rope passing over a pulley, as shown in the figure below. The tension in the rope is 13.9N, and the pulley is 12.3cm above the top of the block. The coefficient of kinetic friction is 0.395. (a: 2.28m/s^2)

*Calculate the value of x at which the acceleration becomes zero*

## The Attempt at a Solution

I dont know where to start with this one. As far as I know, acceleration is zero when the forces in the x direction are zero but i dont know where to start solving this one. Help please!!
