 Two air track carts move along an air track towards each other. Cart A has a mass of 450 g and moves toward the right with a speed of 0.850 m/s and air track cart B has a mass of 300 g and moves toward the left with a speed of 1.12 m/s. What is the total momentum of the system?

450*0.85=382.5...right

300*1.12= 336...left

46.5= 47g= 0.047g

 0.047 kg .m/s toward the right
