Net External Impulse on a System
A 200 g cart traveling at 0.5 m/s collides with a 300 g cart moving at 0.2 m/s in the opposite direction. After the collision, the velocity of the 200 g cart is 0.3 m/s in its original direction. Which statement best describes the net external impulse on the two-cart system during the collision?
A
A force that produced a 0.04 N·s impulse
B
No external force; momentum was conserved
C
A force that produced a 0.08 N·s impulse
D
A force that produced a 0.16 N·s impulse
