A van of mass 3200 kg with velocity +25 m/s collides head on with a sedan of mass 2000 kg with velocity -10 m/s. Calculate the velocity of the sedan after the collision. The van's speed was 0 m/s after the collision? Which of the following is true about the collision between the sedan and the van ?
the gain in momentum of the sedan is numerically the same as the loss in momentum of the van.
the system of the sedan and the van lose momentum from the collision
Impulse of the van is greater than the impulse of the sedan
Impulse of the sedan is greater than the impulse of the van.
