Question

Two cars, with different masses, are traveling forward in the same direction. The car with the greater mass is traveling at a faster velocity.

Assuming a frictionless environmentwhich is true about the total momentum of this system?
A.
The total linear momentum before the collision is less than the total linear momentum after the collision.
B.
The total linear momentum before the collision is one-half the momentum after the collision.
C.
The total linear momentum before the collision equals the total linear momentum after the collision.

Answer 3

here is the rest of D. The total linear momentum before the collision is greater than the total linear momentum after the collision.

Answer 4

any idea @ILUVSOCCER

Answer 5

I think C.

Answer 6

given that momentum is always conserved, i suspect that the answer has something to do with the conservation of momentum.

in which cases does it look like momentum might not be conserved?
