1. The problem statement, all variables and given/known data A boy drags his 60N sled at constant speed up a 15 degree hill. He does so by pulling with a 25N force on a rope attached to the sled. If the rope is inclined at 35 degrees to the horizontal What is the coefficient of kinetic friction between the sled and snow? 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 3. The attempt at a solution Is the correct answer for part 1 .1197? Also when he jumps down, do I include his mass also? It does not cancel out at the end so do I keep it in terms of his mass or go without including? If I get it wrong, I will show my steps.
