A particle of mass m is dropped from a height h above the ground. At the same time 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, the time taken for the combined mass to reach the ground, in units of \sqrt{h/g} is: [8 Jan 2020 Shift 2]
