Question

Two ball bearings of mass m each moving in opposite directins with equal speed v collide head on with each other.predict the outcome of the collision considering them to be perfectly elastic

Answer 1

Yo sup??

since the collision is elastic therefore we can say that the two balls will then move in opposite direction.

If ball 1 was moving from east to west then after collision it will move from west to east

and if ball 2 was moving from west to east then it will start moving from east to west.

Hope this helps.
