If two balls collide in air while moving vertically, then momentum of the sytem is conserved because

A ball is moving towards the wall as shown in diagram then momentum is conserved

A ball is moving towards the wall as shown in diagram then momentum is conserved

A) When a body slides on rough surface, its momentum is not conserved. B) When a ball falls from a height, momentum of earth ball system is conserved C) In case of explosion of flying bomb, momentum is conserved.

Two identical particles collide in air inelastically. One moves horizontally and the other moves vertically with equal speed just before collision. The fractional loss in kinetic energy of the system of particles is equal to
