Thread: Particle of mass, calculate change in K.E.?

a particle of mass 3kg collides another particle of 2kg, their initial velocities are u1= 2i + 1.5j and u2 = 0.25i + 0.8j just before impact. After collision, they both merged and becomes a composite particle, which travel with a velocity of V= 0.6i + 0.7j

calculate the change in K.E.


thanks in advance, I am lost..............
