A body of mass m moving with velocity V in the X-direction collides with another body of mass M moving in Y-direction with velocity v. They coalesce into one body during collision. Calculate :  (i) the direction and magnitude of the momentum of the final body.  (ii) the fraction of initial kinetic energy transformed into heat during the collision in terms of the two masses.
