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)`.
