## 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:

**2.28 m/s^2**

Calculate the value of

Calculate the value of

*x*at which the acceleration becomes zero. <-- this is what i'm stuck on## Homework Equations

## The Attempt at a Solution

I know when acceleration is equal to zero, it means that the forces in the x and y direction are equal to zero, but that is as far as i know of how I can complete this. Any suggestions?
