B is the answer??
May be it's very basic but i want to know how you break those components there is no angle given?
Thanks @Samarth_2020 for your precious time.
Why not C?
Yes c is only possible
Even if elastic collision occurs it cannot return.
Yes I didn't read 'cannot return'
Well, given answer is A
That's the main point it doesn't mentions type of collision
Yes it is possible when the collision is elastic.
