A projectile is projected in horizontal direction with velocity u from height h. How long will it take to reach the ground?

Velocity of the particle = uÂ

Height at which the particle is projected = h

Let, time of flight be T

Using the equation,Â

y = yo +uyt +Â

We have, y=h, yo = 0 and uy = 0Â

Therefore,Â

h = 0+0Â

Time taken for the particle to reach the ground, T =Â
