Please answer b.

(8%) Problem 9: A block of mass m = 3.5 kg is attached to a spring with spring constant k = 640 N/m. It is initially at rest on an inclined plane that is at an angle of 0 = 270 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.19. In the initial position, where the spring is compressed by a distance of d = 0.12 m, the mass is at its lowest position and the spring is compressed the maximum amount. Take the initial gravitational potential energy of the block as zero. M Otheexpertta.com @theexpertta.com - tracking id: 5T88-19-A0-48-9B40-47948.

DA 50% Part (b) If the spring pushes the block up the incline, what distance, L in meters, will the block travel before coming to rest? The spring remains attached to both the block and the fixed wall throughout its motion.
