355333 A mass ' \(m\) ' moves with a velocity \(v\) and collides inelastically with another identical mass. After collision the \({1^{st}}\) mass moves with velocity \(\dfrac{v}{\sqrt{3}}\) in a direction perpendicular to the intial direction of motion. Find the speed of the \({2^{nd}}\) mass after collision.
