Now i figured out using lol diagram that es would be equal to ek so then Ek=.5*m*V^2 and found the velocity not using the momentum. Anyone think what i did was wrong?

When i drew the momentum bar graph, i set spring as the impulse so there was no momentum in beging but some at the end.

Mass of cart A: 1kg Mass of Cart B: 3Kg Spring potential energy: 24 Joules Two carts are pushed apart when the spring is released. Thats all the given and I'm suppose to find the final velocity. I have no idea how to get started. For me to use Es=(1/2)K*DeltaX^2, i don't have delta x or...
