Answer :
We are given that an egg is thrown against a wall. The initial momentum of th egg is:
[tex]p=mv[/tex]Where "m" is the mass and "v" is the velocity. Whe n the egg hits the wall that is a force that acts on the egg. Therefore, the change in momentum is:
[tex]I=p_f-p_0[/tex]This mean that the momentum is not conserved because there is an outide force that is causing an impulse "I". Therefore, the right answer is A.
