1. The problem statement, all variables and given/known data 7. A boy drags his 60.0-N sled at constant speed up a 15.0° hill. He does so by pulling with a 25.0-N force on a rope attached to the sled. If the rope is inclined at 35.0° to the horizontal, (a) What is the coefficient of kinetic friction between sled and snow? (b) At the top of the hill, he jumps on the sled and slides down the hill. What is the magnitude of his acceleration down the slope? 2. Relevant equations See Below 3. The attempt at a solution For question b, I ended up getting a result that should mean the sled is accelerating up the hill at ##2.29m/s^2##. Can someone look over my work? I was not sure what "If the rope is inclined at 35.0° to the horizontal" meant. I assumed it meant that the angle was relative to tilted axes.
