A .50-kg block, starting at rest slides down a 34.0 degree incline with kinetic friction coefficient 0.20. After sliding 85 cm down the incline, it slides across a frictionless horizontal surface and encounters a spring (k= 350 N/m).
A) what is the maximum compression of the spring?
B) After compression of part a, the spring rebounds and shoots the block back up the incline. How far along the incline does the block travel before coming to rest?
