When a projectile is fired at an angle and it lands at the same elevation from which it was launched, ∆y = 0, and we may solve Equation (2) for t: t = 2v yo/g (2b) Substituting this into Equation (1) yields ∆x = 2v xv yo/g = 2(2v cosθsinθ)/g (3) where v is the initial speed of the projectile.

An optimal angle of take-off will allow the swimmer to increase their potential flight distance, thereby increasing their performance. If the take off angle is too high, the angle of entry will be steep, leading to a deep gliding pattern, requiring more time to return to the surface and reducing the flight distance.
