1. The problem statement, all variables and given/known data A box is sliding up an incline that makes an angle of 18.0° with respect to the horizontal. The coefficient of kinetic friction between the box and the surface of the incline is 0.180. The initial speed of the box at the bottom of the incline is 2.30 m/s. How far does the box travel along the incline before coming to rest? 2. Relevant equations F = ma 3. The attempt at a solution I tried to figure out the Normal Force so that I could figure out the force of friction, and thus determine the acceleration. However, I don't have the mass of the box so I cannot figure out the Normal force.
