Assuming that the collision between Object A and Object B occurs in an isolated system, which of the following statements are consistent with this law? Select the two true statements. HINT: Consider Newton's 3rd Law of forces come in pairs and are equal and opposite. J a Object A will have the same momentum as Object B both before and after the collision. b The total momentum of Objects A and B will be the same before and after the collision. Object A's momentum before the collision is the same as it is after the collision. O d The change in Object A's momentum will equal and opposite to the change in Object B's momentum.
