is given an initial speed of 3.9 m/s up a 17

◦

incline. The combined mass of the monkey

and the sled is 18.1 kg, and the coeﬃcient

of kinetic friction between the sled and the

incline is 0.34.

The acceleration of gravity is 9.81 m/s

2

.

How far up the incline does the sled move?

Answer in units of m

**drwls**, Monday, December 17, 2012 at 6:10amUse conservation of energy

(Increase in potential energy) = (Initial kinetic energy) + (work done against friction)

Let L be the length it goes up the incline.

M*g*L*sin 17 = (1/2)*MVo^2 + M*g*L*cos17*(mu_k)

mu_k is the kinetic friction coefficient, 0.34

Cancel out the M's and solve for L
