1. The problem statement, all variables and given/known data A 1.0 Kg cart moving at 4.0 m/s overtakes and collides with a 3.0 kg cart moving in the same direction at 2.0 m/s on the same track. Given that these carts collide elastically due to repelling magnets, determine the maximum energy stored in the magnetic field. 2. Relevant equations Ke = 1/2mv^2 Ktotal = Ke + Ke 3. The attempt at a solution Hey guys, I have an exam tomorrow and can't seem to figure this out. I found the total kinetic energy in the system, to be at 14 J. However, I do not know what to do from here on.
