B. speed is mainly concentrated in the bullet.
C. rifle has lots of mass.
D. momentum of the rifle is unchanged.
E. none of these A. it depends on the initial velocity of the bug
B. the car
C. the bug
D. both experience the same changeE. none of the above A. Sudden stops have bigger impulse
B. Sudden stops have less time for momentum change
C. Force pairs are not equal
D. Because you have more inertia A. Resistance to a change motion
B. Force on an object to move
C. What keeps you moving when a car
