Three objects 
and C, are kept in a straight line on a frictionless horizontal surface. These have masses 
m, and 
, respectively. Object A moves towards B with a speed of 
and makes an elastic collision with it. After that, B makes a completely inelastic collision with C. All motions occur on the same straight line. Find the final speed (in 
) of object V.
