Q2) There are 3 blocks whose masses are m, 2m and 3m on the smooth surface. The first one has a velocity v and others connected to spring are at rest. The spring force is not impulsive. If the coefficients of restitution and spring are respectively e and k, a) What is the maximum elongation (or shortening) of spring? b) What is the minimum value of kinetic energy of system? Hint:Equations can be built according to the moving axis with the origin at the center of mass of the bloks connected to the spring. m V 2m k 3m
