Forcing Objects to Change

SATPHY-9KAFGJ

The graphs below show the net force applied to two different objects (one blue and one purple) along a straight line over the same time period. How do the changes in momentum compare for these two objects?

A

The purple object's momentum changes slightly more than the blue object's momentum.

B

The purple object's momentum changes about twice as much as the blue object's momentum.

C

The blue object's momentum changes slightly more than the purple object's momentum.

D

The blue object's momentum changes about twice as much as the purple object's momentum.

E

We cannot determine how much the momentum of either changes without knowing the masses of the objects and their velocity changes.
