Question

Which of the following statements is true about a collision between two cars in the absence of outside forces? (1 point) The total momentum after the collision is the same as the total momentum before the collision.The total momentum after the collision is greater than the total momentum before the collision.The total momentum after the collision is less than the total momentum before the collision.The total momentum after the collision is zero.

Answer 1

Total momentum is conserved only if the collision can be considered isolated from the influence of net external forces. So, in our case because there is absence of outside forces the total momentum is conserved.

The following statement is true:

The total momentum after the collision is the same as the total momentum before the collision sooo C

Answer 2

Total momentum is conserved only if the collision can be considered isolated from the influence of net external forces. So, in our case because there is absence of outside forces the total momentum is conserved.
The following statement is true:
The total momentum after the collision is the same as the total momentum before the collision
