Two billiard balls, assumed to have identical mass, collide in a perfectly elastic collision. ball a is heading east at 12 m/s. ball b is moving west at 8.0 m/s. determine the post-collision velocities of ball a and ball b.

Ball A will move towards West with speed 8 m/s

Ball B will move towards East with speed 12 m/s

Explanation:

As we know that during collision there is no external force on the system

So here we can use momentum conservation for finding the final velocities of two balls

so we have

since two balls are identical so we have

also we know that for elastic collision we have

so we have

so we have

Towards East

Towards West

not sure 12

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right
