u wanna know something about collisions...then read this.... collisions 1D... consider two smooth, non rotating spheres of masses m1 and m2. moving along a straight line joining the centre of masses moving with initial velocities u1 and u2 and final velocities v1 and v2. let the collision be elastic. In an elastic collision both momentum and kinetic energy are conserved. according to the law of conservation of monemtum.... m1u1+m2u2=m1v1+m2v2 m1u1-m1v1=m2v2-m2u2 ----- 1 accroding to conservation of kinetic energy...
