Two balls collide in a closed system. The initial and final mass and velocity quantities for each ball are provided in the illustration. Because momentum is conserved, it can be concluded that the final velocity of the smaller ball will be which of the following?

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
