Ignore air resistance and consider the flight of each object from launch until it returns to the same launch height above the ground. Which object experiences the greatest change in the linear momentum?

A. Object 1 since it has a higher final speed.
B. Object 2 since it has a higher final speed.
C. Object 2 since it is in the air for a longer time.
D. The change in momentum is the same for each.
