Find the total airborne time of a projectile launched from level ground.

The math behind it

t = 2·v₀·sinθ ÷ g, double the time it takes to reach the top of the arc.

Worked Example

20 m/s at 45° → 2.88 s.

Frequently Asked Questions

Does mass affect the time?

No — ignoring air resistance, only the vertical velocity and gravity matter.
