A spring rest on a 30o incline, its uncompressed length is 0.8 meter. A 2 kilogram mass is located on the incline and pushed down therefore that the spring is compressed 0.6 meter from its equilibrium position. Its coefficient of kinetic friction between the mass and the incline is 0.2 and the block moves up the incline 1 meter after the spring is released, determine what is the spring constant K.
