1. Think about what would happen to total kinetic energy and you will know the answer.
2. Calculate the final velocity Vf using the law of conservation of momentum, which must be obeyed.
10*4 - 4*4 = 14*Vf
14*Vf = 24 kg*m/s
Vf = +1.714 m/s (+ is to the right)
Now compare initial and finalkinetic energies. That is something you should do yourself.
