A body is projected with velocity u at an angle θ and reaches the ground at time T. What will be the time of flight if the body is projected with same speed at an angle (90°–θ)?

Time of flight for angle of projection is given by,

...(1)

If the body is projected at an angle , then the time of flight T' is

...(2)

Dividing (2) by (1), we get
