Explanation / Answer

If we launches a projectile horizontally. Assume that the initial speed of projectile is zero.

The projectile accelerates after launching it only by gravitational force. And acceleration of projectile is equal to acceleration due to gravity.

Using kinetimatic equation.

y=v_0*t+1/2*a*t^2

y=0*t+1/2*g*t^2

t^2=2y/g

t=2y/g
