Ball A Momentum Before Collision

Question

8 kg mis

Ball B Momentum Before Collision

4 kg m/s

Total Momentum of Both Balls After Collision

12 kg m/s

Does the data in the table demonstrate the law of conservation of momentum?

(1 point)

Yes, because the total momentums before and after the collision are equal.

Yes, because the total momentums before and after the collision are unequal

No, because the total momentums before and after the collision are equal

No, because the total momentums before and after the collision are unequal.

Answer 1

To determine if the data demonstrates the law of conservation of momentum, we first need to calculate the total momentum before the collision and compare it with the total momentum after the collision.

1. Total Momentum Before Collision:

   • Momentum of Ball A: 8 kg m/s
   • Momentum of Ball B: 4 kg m/s
   • Total momentum before collision = Momentum of Ball A + Momentum of Ball B = 8 kg m/s + 4 kg m/s = 12 kg m/s.

2. Total Momentum After Collision:

   • Given that the total momentum after the collision is 12 kg m/s.

Since the total momentum before collision (12 kg m/s) is equal to the total momentum after collision (12 kg m/s), this demonstrates the law of conservation of momentum.

Therefore, the correct answer is:

Yes, because the total momentums before and after the collision are equal.
