1. The total momentum of the two race cars before a collision is 600kg m/s. What is the total momentum of the two race cars after they collide?
0kg m/s
150kg m/s
300kg m/s
600kg m/s
600kg m/s anyways the answers for the test are
A. The ball won't move until there is an outside force acted upon it like a kick
B. Force= mass x acceleration
D. 1N
A.45kg m/s
A. 600kg m/s

momentum is conserved, right?
i think so
To find the total momentum of the two race cars after they collide, we need to understand the principle of conservation of momentum. According to this principle, the total momentum before a collision is equal to the total momentum after the collision.
In this case, the total momentum before the collision is given as 600 kg m/s. Therefore, the total momentum after the collision will also be 600 kg m/s.
So, the correct answer is 600 kg m/s.
