A body of mass m is falling freely through a height h from the top of a tower.The velocity just before touching the ground is `sqrt((3/2)gh)` .The work done by air drag is?

A body is dropped from a height equal to radius of the earth. The velocity acquired by it before touching the ground is

A stone is released from the top of a tower of height 19.6m. Calculate its final velocity just before touching the ground.

A body of mass 'm is drhopped from a height 'h'. The speed with which body hits the ground is sqrt(0.9gh) Find the work done by air-resistance furing its fall.

A body of mass m is projected horizontally with a velocity v from the top of a tower of height h and it reaches the ground at a distance x from the foot of the tower. If a second body of mass 2m is projected horizontally from the top of a tower of height 2h, it reaches the ground at a distance 2x from the foot of the tower. The horizontal velocity of the second body is :

A body of mass m is projected horizontally with a velocity v from the top of a tower of height h and it reaches the ground at a distance x from the foot of the tower. If a second body of mass 2 m is projected horizontally from the top of a tower of height 2 h , it reaches the ground at a distance 2x from the foot of the tower. The horizontal veloctiy of the second body is.

A body of mass m when released from rest from a height h, hits the ground with speed sqrt(gh) . Find work done by air resistance force.

A body is released from the top of a tower of height 50 m. Find the velocity with which the body hits the ground. (g=9.8m//s^(2))
