A body A of mass 4 kg is dropped from a height of 100 m. Another body B of mass 2 kg is dropped from a height of 50 m at the same time. Then :

Body A of mass M is dropped from a height of 1 m and body. B of mass 3M is dropped from a height of 9 m. The ratio of time taken by the bodies 1 and 2 to reach the ground is

Body 1 of mass M is dropped from a height of 1 m and body 2 of mass 3 M is dropped from a height of 9 m. Ratio of time taken by bodies 1 and 2 to reach the ground is

A body is dropped from a certain height.

A body of mass m is dropped from a height of h . Simultaneously another body of mass 2m is thrown up vertically with such a velocity v that they collide at height h/2 . If the collision is perfectly inelastic, the velocity of combined mass at the time of collision with the ground will be
