Here is a hw problem that I am unsure of.

You have a 100kg cart A moving to the right at 8m/s toward a 200kg cart B at rest that is connected to a spring. the two carts move together after impact. (I assume this implies perfectly inelastic collision.) Neglect friction. Spring constant is 3000 N/m

Find the velocities after impact, spring deflection (what is meant by this?), and energy lost during the impact.

pic is my attempt but I am unsure about the energy loss part. Thanks
