A girl is sitting on a sled. She is pushed by a spring that was compressed 0.8m. The spring constant is 2500 N/m. After moving 2.5 m across a surface that applies 60 n of friction, the girl and the sled slid up a frictionless hill. The mass of both the sled and the girl is 27kg. How high do the girl and the sled rise up by the time they stop?

do this as consrevation of energy
Initial spring energy=workdoneFriction+PE gain at top
1/2 k x^2=60*2.5+mass*g*height solve for height
