A mass 'm' moves with a velocity 'v' and collides inelastically with another identical mass. After collision the Ist mass moves with velocity \[\frac{v}{\sqrt{3}}\] in a direction perpendicular to the initial direction of motion. Find the speed of the 2nd mass after collision [AIEEE 2005]

• A.          \[\frac{2}{\sqrt{3}}v\]
• B.                        \[\frac{v}{\sqrt{3}}\]    
• C.          v   
• D.          \[\sqrt{3}\,v\]
