Ball A and Ball B are rolled so that they will collide. Does the data in the table below demonstrate the law of conservation of momentum?
Ball A Momentum Before Collision= 3 kg m/s
Ball B Momentum Before Collision= 2 kg m/s
Total Momentum of Both Balls After COllision- 6 kg m/s
A. Yes, because the total momentums before and after the collision are equal.
B. Yes, because the total momentums before and agter the collision are unequal.
C. No, because the total momentums before and after the collision are equal.
D. No, because the total momentums before and after the collision are unequal.
Is the answer D?
Thank you

My short answer question haven't been graded yet so I don't know if they're right but I'm going to post them anyways.
24.His first law claims that if an object is in motion, it will stay in motion and if it's not in motion, it stay at rest. If the car is moving our bodies are going to move. Moving at every bump and stop.The seat belt helps to stop movement so our bodies can avoid injury.
25.Before the skydiver opens the parachute, gravity will be pulling them unto the ground. Once they open the parachute, the air resistance will try to pull the skydiver up to resist him or her falling unto the ground very hard. Gravity will pull the skydiver down unto the ground until the skydiver actually makes it with the increase of air resistance making their landing safer than before.
