1. The problem statement, all variables and given/known data 30g object slides on slope of 20 degrees, with kinetic coefficient of .20. Object is launched up from a spring at bottom of slope, which was compressed by 10 cm. Spring constant = 25 N/m. Find the total distance object travels up slope before reversing direction. 2. Relevant equations i don't know where to start with this. I tried equations of energy according to conservation of energy. 3. The attempt at a solution initial: .5kx^2 final: mgh therefore mgh=.5kx^2 Then i rearranged for height. h=(kx^2/2mg) however, i think this is the wrong thing to do. I havn't even used the friction coefficient. Please help me get on the right track with this problem. Thanks in advance.
