1. The problem statement, all variables and given/known data 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? 2. Relevant equations mk= Fnormal*ms 3. 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.
