Academics

A crate of mass 0.812 kg is placed on a rough incline of angle 35.3^o . Near the base of the incline is a spring of spring constant 1140 N/m. The mass is pressed against the spring a distance x and released. It moves up the slope .285 meters from the compressed position before coming to a stop. If the coefficient of kinetic friction is 0.195, how far (m) was the spring compressed?
