Question
a projectile returns to its original height after 4.08 seconds, during which tie it travels 6.2 meters horizontally. If air resistance is ignored, what was the projectile's initial speed?

horizontal velocity (vh) = 6.2 m / 4.08 s
initial vertical velocity (vv)
... = (4.08 s / 2) * g
(initial speed)^2 = vh^2 + vv^2
initial vertical velocity (vv)
... = (4.08 s / 2) * g
(initial speed)^2 = vh^2 + vv^2
