According to V=(2gh) 1/2 ,an object falling from a great height should have a very high velocity. That means a raindrop and a hailstone should hit the ground very hard with a terrible speed.But why doesnt that happen?

Hi Chilukuri Kartik 

That relation V=(2gh)1/2 is drive for ideal case.

in derivation of this formula we have not consider the effect of drag forces.

Drag force acts in the reverse direction of the movieng particle.the more the velocity the more will be drag force.so it reduce the velocity of moving particle..

Thats why a raindrop and a hailstone should  not hit the ground very hard
