1. The problem statement, all variables and given/known data A block slides down a hill. The hill has a gentle 20° slope with respect to the horizontal. The block has an initial speed of 6 m/s. If the block comes to a stop after traveling a total distance of 11 m along the slope, what is the coefficient of kinetic friction between the block and the hill? 2. Relevant equations F=ma Fk=μk*n 3. The attempt at a solution The first thing I did was draw a FBD. The box is going forward in the positive direction so the kinetic friction is acting in the opposite direction. There is force of gravity acting on the box and normal force, these forces are in the opposite direction on y axis. My x axis with was with respect to the slop, so kinetic friction is in the negative direction and the box is in position direction, on the x axis. Now I don't know what to do next...help?
