A light particle moving horizontally with a speed 12 m/s strikes a very heavy block moving in the same direction at 10 m/s. The collision is one dimensional and elastic. In elastic collision, the conservation of momentum and conservation of kinetic energy are valid. After the collision, the particle will ……

8m/s is the velocity bywhich the lighter particle will move. as one mass is large.......we could use the formula V2=2U1-U2.......where v2 is velocity of second mass
