order for the cars to completely stop when they collide, which of the following is true?
(Remember, Momentum = mass * velocity)


A.) Car A should have twice the velocity of Car B

B.) Car B should have twice the velocity of Car A

C.) Car A should have 4x the velocity of Car B

D.) Car B should have 4x the velocity of Car A

Please help

Answer 1

A

If Car A has half the mass of Car B, then it must have twice the velocity to come to a stop when colliding.
