Question

A steel ball moving with velocity v' collides elastically with an identical ball originally at rest.the velocity of the first ball after the collision is:

Answer 1

Explanation:

I hope this answer helpful

Answer 2

Answer:

The velocity of the first ball after the collision will be 0 m/s.

Explanation:

Given;-

         Initial Velocity of A = v m/s

          Initial Velocity of B = 0 m/s

We know that, in elastic collision of two objects having same mass, the velocities before collision are interchanged by the velocities after collision.

So,      Final velocity of A = 0 m/s

          Final velocity of B = v m/s

Therefore, the velocity of the first ball after the collision will be 0 m/s.
