Question

Define elastic collision. With the help of neat diagram obtain the

expressions for final velocities in terms of initial velocities.
​

Answer 1

Explanation:

Elastic collision In a collision ,the total initial kinetic energy of the bodies (before collision ) is equal to the total final kinetic energy of the bodies (after collision) then, it is called as elastic collision . i.e., Total kinetic energy before collision = Total kinetic energy after collision .
