Homework Statement
In a circus performance, a monkey is strapped to a sled and both are given an initial speed of 4 m/s up a 20 degree inclined track. The combined mass of monkey and sled is 20 kg and the coefficient of friction between the sled and incline is .20. How far up the incline do the monkey and sled move?
Homework Equations
Potential energy gravity = mg(delta h)
Work of Friction = force x X
Kinetic energy = .5mv2
F perpendicular = fgcostheta
F parallel = fgsintheta
The Attempt at a Solution
I'm having the most trouble just coming up with the equation to use. As the monkey moves up he gains potential gravitational energy. He also loses some kinetic energy to the work of friction. I'm also not sure what to plug in for work of friction.
