Two 2 kg balls move away from each other,
one traveling 3 m/s to the right, the other
5 m/s to the left.
What is the magnitude of the total momentum of the system?
Answer in units of kg · m/s
is the equation for this p=mv?

Question

Two 2 kg balls move away from each other,
one traveling 3 m/s to the right, the other
5 m/s to the left.
What is the magnitude of the total momentum of the system?
Answer in units of kg · m/s
is the equation for this p=mv?

anonymous · Answer

Yes P = mv  where you use the total mass and the difference of velocities

anonymous · Answer

one would be 6 and the other 10 but I'm not sure if you add or subtract to find total momentum since they are moving in different directions
