Question

Q.24
Define elastic collision in one dimension . Obtain
expression for
velocities of the two bodies after such collision
​

Answer 1

Answer:

In Case of the Elastic Collision, Kinetic Energy before and after the collision remains the conserved, momentum also remains conserved.  

On This basis, Derivation in One dimension is shown in attachment.

The body of mass m₁ is moving with the velocity u₁ and body of mass m₂ is moving with velocity u₂, after the collision there velocity became v₁ and v₂.

The Final Result is,

v₂ - v₁ = u₁ - u₂.

Hope it Helps.
