    velocities are given in terms of c that's I used relativistic concept..

    first see, it's a inelastic collision and they combined after collision...using law of conservation of momentum, then p1+p2=p---> p1=0 so p2=p.. then using conservation of energy E1+E2=E using this two , u get M( keep in mind that E^2=p^2c^2+mo^2c^2)....... p2=p and E1=(M1*c^2) and E2=((p2*c)^2+(M2*c^2)^2)^1/2 and similarly E=((pc)^2+(Mc^2)^2) where M is the combined mass.. using all these u will get combined mass after collision.. try to do by urself Even then u find any difficulty do let me know..

    Question is incomplete. The question should be - A body of rest mass mo collides perfectly inelastically at a speed of 0.8c with another body of equal rest mass kept at rest. Calculate the common speed of the bodies after the collision and the rest mass of the combined body. See the attached file for answer.
