A mass ‘𝑚’ moves with a velocity ‘𝑣’ and collides inelastically with another identical mass. After collision the Ist mass moves with velocity 𝑣 √3 in a direction perpendicular to the initial direction of motion. Find the speed of the 2nd mass after collision

Question: A mass ‘𝑚’ moves with a velocity ‘𝑣’ and collides inelastically with another identical mass. After collision the Ist mass moves with velocity 𝑣 √3 in a direction perpendicular to the initial direction of motion. Find the speed of the 2nd mass after collision

(A) \dfrac{2}{\sqrt{3}}v

(B) \dfrac{v}{\sqrt{3}}

(C) 𝑣

(D) \sqrt{3}v

Answer: Option (A)

Solution:

A mass ‘𝑚’ moves with a velocity ‘𝑣’ and collides inelastically with another identical mass. After collision the Ist mass moves with velocity 𝑣 √3 in a direction perpendicular to the initial direction of motion. Find the speed of the 2nd mass after collision
