A mass m moves with a velocity v and collides inelastically with another identical mass. After collision the Ist mass moves with velocity \(\frac{\mathrm{v}}{\sqrt{3}}\) in a direction perpendicular to the initial direction of motion. Find the speed of the 2nd mass after collision :
- \(\frac{2}{\sqrt{3}} \mathrm{v}\)
- \(\frac{\mathrm{v}}{\sqrt{3}}\)
- v
- \(\sqrt{3} v\)
Answer
(A) 2 3 v
