drops are falling regularly from a water tap at a height of 9m from the ground. the fourth drop is about to fall from the tap when the first hits the ground.find the distance between second and third drop.

when we throw a ball on a wall at some angle and it rebounds back with same velocity there is change in momentum. so how we can say law of conservation of momentum is obeyed there??
