A cart moving to the right with a momentum of magnitude 5.34 ± 0.04 kg*m/s collides with a second cart moving to the left with a momentum of magnitude 8.40 ± 0.01 kg*m/s. What is the magnitude of the total momentum after the collision?

OpenStudy (anonymous):

i think you take the resulting magnitude, which is towards the left with a magnitude of: 5.34 - 8.40 = -3.06 kg*m/s

so what would be the uncertainty?
