Cart A and B are equal mass ( 500 kg each) and have frictionless wheels. Cart A has a spring attached to its end with a constant 2000 N/m. Cart B has a spring constant attached to its end with a different spring constant. They both sit on a track with their spring facing each other, and are pushed together and held so that each of the springs are compressed 10 mm. When released, Cart A moves away with a speed of 0.9375m/s

a. Find the speed of Cart B after the two are released

b. Predict the spring constant of Cart B's spring ( friction should be ignored and use conservation of energy for this)

This is my assignment needs to be handed in last Fri. Even though I tried so hard, I couldnt get the right answer. I handed that in, but I think my answer for the spring constant of B was wrong. I didnt use 2 dimention aspect to solve this though. I'm really confused...Can someone help me please...Thank you
