Let’s cоnsider аn elаstic cоllisiоn between two mаrbles, where the marbles are confined to one dimension. Suppose marble 1 with a mass of 40 g is shot with a speed of 5 m/s into marble 2 with a mass of 20 g. What will be the speed of marble 2 after the collision? ( Hint: This is a special case of the one dimensional elastic collision discussion in the ppt slides).
