- Homework Statement
- 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.

I've found M-k it is 0.16

how to find the acceleration? I can't solve it without the quetion telling me the mass of the kid!
