A boy drags his 8.00 kg sled at constant speed up a 10.0 degree hill. He does so by pulling with a 40.0-N force on a massless rope attached to the sled. If the rope is inclined at 40.0 degrees to the horizontal,

a) Draw two separate free body diagrams for the sled and the boy.

b) Considering the boy, sled, rope, and earth identify at least 5 action reaction pairs. 1)....... 2)...... 3)....... 4)...... 5)........ List more for extra points.

c) What is the normal force that the hill exerts on the sled?

d) What is the magnitude of the friction force that acts on the sled?

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