## Homework Statement

A box is sliding down an incline tilted at a 13.0° angle above horizontal. The box is initially sliding down the incline at a speed of 1.40 m/s. The coefficient of kinetic friction between the box and the incline is 0.370. How far does the box slide down the incline before coming to rest?

## Homework Equations

mk= Fnormal*ms

## The Attempt at a Solution

1.4 m/s in x direction= m*cos(13)

m=1.4368

m*ms= 1.4368*.37=.51363= mk

1.4m/s-.51368mk= .868m

Not sure what I am doing wrong. Thanks.
