Set a weighted 3 kg atop a frictionless incline. When sliding to the bottom with an inclined plane, the toxin weight K = 400 N/m is placed horizontally. Assume that the system loses mass due to friction. a –Find the compression ∆x of the spring –If the horizontal surface of the system is close to k = 0.2, how far will the 10th weight slide before coming to a complete stop?
