I think the combined velocity of the two particles is determined by applying conservation of momentum by you. And I am considering the value of final velocity, v = 2.6782 m/s is correct.
Now for part (b) -
Total initial energy, KEi = kinetic energy of first particle + kinetic energy of the second particle
= (1/2)*m1*v1^2 + (1/2)*m2*v2^2
= 0.5*2.0*15^2 + 0.5*2.6*(-6.8)^2
= 225 + 60.11 = 285.11 J
Total final energy of the two particle after collision, KEf = (1/2)*(m1+m2)*v^2
= 0.5*(2.0+2.6)*2.6782^2
= 16.50 J
Therefore, amount of kinetic energy lost in the collision = KEi - KEf
= 285.11 J - 16.50 J = 268.61 J (Answer)
