Acceleration due to gravity (g)
To find:-The time of the flight, neglecting the air resistance.

When the body comes back to the initial position, the displacement s = 0
We know that,
s = ut – 1/2gt
t = 2u/g. Here ‘t’ is the time of flight, i.e.,
Therefore, Time of flight, t =
Thus, time of flight neglecting the air resistance=4s
