How do you get the velocity after a collision if one body towards left have a mass of 5kg while the other body with a mass of 10kg with a velocity of 2m/s towards right. How do you find the velocity of the body with the mass of 5kg towards left?

If that is a post collision diagram, the speed of the 5kg mass would depend upon the initial momentum of the system ...
