A body of mass m is dropped from a height h simultaneously another body of mass 2m is thrown up vertically with velocity V such that they collide at height `h/2` if collision is perfectly inelastic then speed with which the combined mass system hits the ground is?

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

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

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 :

A ball of mass m is thrown vertically up with an initial velocity so as to reach a height h.The correct statement is :

A body of mass 'm' moving with certain velocity collides with another identical body at rest. If the collision is perfectly elastic and after the collision both the bodies moves

A stone is dropped from a height h. simultaneously, another stone is thrown up from the ground which reaches a height 4h. The two stones will cross each other after time:-

A particle of mass m is dropped from a height h above the ground. At the same time another particle of mass 2m is thrown vertically upwards from the ground with a speed of sqrt(gh) . If they collide head-on completely inelastically, the time taken for the combined mass to reach the ground, in units of sqrt(h/g) is:

A particle of mass m is dropped from a height h above the ground. At the same time another particle of mass 2m is thrown vertically upwards from the ground with a speed of sqrt(gh) . If they collide head-on completely inelastically, the time taken for the combined mass to reach the ground, in units of sqrt(h/g) is :

A particle of mass m is dropped from a height h above the ground. Simultaneously another particle of the same mass is thrown vertically upwards from the ground with a speed of sqrt(2gh) . If they collide head-on completely inelastically, then the time taken for the combined mass to reach the ground is

A particle of mass 2m is dropped from a height 80 m above the ground. At the same time another particle of mass m is thrown vertically upwards from the ground with a speed of 40 m/s. If they collide head-on completely inelastically, the time taken for the combined mass to reach the ground, in units of second is:
