There are two identical particles A and B. One is projected vertically upward with speed `sqrt(2gh)` from ground and other is dropped from height h along the same vertical line. Collision between them is perfectly inelastic. Find time taken by them to reach the ground after collision in terms of `sqrt(h/g)`.

Two iron and wooden balls identical in size are released from the same heilght in vacuum. The time taken by them to reach the ground are:

A wooden ball and an iron ball are dropped from the same height h in vaccum. If their radii are the same then the time taken by then to reach the ground are

A ball is thrown vertically upward with a speed v from a height h above the ground . The time taken for the ball to hit the ground is

A helicopter rises from rest on the ground vertically upwards with a constant acceleration g. A food packet is dropped from the helicopter when is at a height h. The time taken by the packet to reach the ground is close to [ g is the acceeration due to gravity] :

Two identical masses are as shown in figure. One is thrown upwards with velocity 20 m/s and another is just dropped simultaneously. If the collision between them is elastic, find the time interval between their striking with ground

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 :
