A 0.50-kg block rests on a horizontal, frictionless surface, it is pressed against a light spring having a spring constant of k = 800 N/m, with an initial compression of 2.0 cm. To what height h does the block rise when moving up the incline? what would be the h if the coefficient of the kinetic friction is 0.1 and the angle is 15 degrees ?
