@Nurali do you think you could help me with this?

Linear momentum should be conserved. m1*v1 + m2*v2 = (m1 + m2)*v' Suppose you don't know the final velocity, then: http://www.wolframalpha.com/input/?i=%282.1*2.9%29+%2B+%2837*-3.1%29+%3D+%282.1+%2B+37%29*v Read: http://en.wikipedia.org/wiki/Inelastic_collision

Inelastic collisions mean the objects have fused together, so they share the same final velocity. When this happens, some kinetic energy is converted to heat generally, so the momentum is conserved but kinetic energy is not.
