If two carts collide and cart 1 has a spring on it, how can I figure out the final velocity of the first cart????
I thought you said they collided?the carts are initially at rest together, then the spring on cart 1 is released.
Momentum, yes. Kinetic energy, no. (They start at rest, then begin to move.) Hint: Consider the energy stored in the compressed spring.kinetic energy and momentum
