Problem 3 The 12-kg box A is traveling at 10m/s when 10 m/s * = 1000 N/m it is s = 3 m from box B. It travels on a surface with # = 0.2. If box B has a mass of 8-kg, determine the maximum compression of the spring due to the collision when e = 0.4. The stiffness coefficient of the spring is k =1000 N/m
