Suppose the total momentum of two masses before a collision is 100 kg m/s. What is the total momentum of the two masses after they collide?
A. 0 kg m/s
B. 50 kg m/s
C. 100 kg m/s
D. 200 kg m/s
Total momentum before the collision =
Total momentum after the collision.
C. 100kg m/s.
To find the total momentum of two masses after a collision, we need to consider the law of conservation of momentum. According to this law, 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 100 kg m/s. Therefore, the total momentum after the collision will also be 100 kg m/s.
So, the correct answer is C. 100 kg m/s.
