Problem P. 3937. (December 2006)

P. 3937. Two wagons of masses m1 and m2 are moving towards each other along a horizontal path. Their speeds are v1 and v2 respectively. a) What is their common velocity after they are hitched? b) What is the maximum compression of each buffer if the spring constant of all the four buffers are the same D? c) If the sum of the masses of the two wagons is constant at what ratio of the masses will the maximum compression be the greatest?
