Problem 7: A block of mass m = 3.5 kg is attached to a spring with spring constant k = 850 N/m. It is initially at rest on an inclined plane that is at an angle of 8 = 290 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μ = 0.19. In the initial position, where the spring is compressed by a distance of d = 0.13 m, the mass is at its lowest position and the spring is compressed the maximum amount. Take the initial gravitational energy of the block as zero.
