Cart A (mass 10kg) and cart B (mass= 10kg) are connected by a compressed spring. When the spring is released, cart A has a velocity of 5m/s east. Find:
a. momentum of cart A
b. momentum of cart B
c. velocity of cart B

I will be happy to critique your thinking.
The initial momentum is zero, so the sum of car A and carB must be zero. You are given momentum of Car A (mass*volume)
