8.1) This illistration illistrates that a larger change in t for an applied force will result in a greater momentum. It also illistrates that an increase in mass will not change momentum in the same way velocity changes.

8.2) Kinetic energy is also unaffected by mass but is my a change in time of the force applied.

8.3) For a "hard" collsion, when both balls have the same mass, their collision causes each to rebound with opposite velocities. Any time one ball's mass is three times that of the other, the one with the larger mass will lose all it's velocity. No matter what, total momentum is conserved.
