**Classical Mechanics**Level 2

A body is thrown vertically upwards from A, the top of a tower. It reaches the ground in time \(t_1\). If it is thrown vertically downwards from A with the same speed, it reaches the ground in time \(t_2\). If it is allowed to fall freely from A, then the time taken to reach the ground is given by?
