. 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) Draw a free body diagram for the problem.  

(b) What is the coefficient of kinetic friction between sled and snow?   

(c) 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?
