# If a projectile flies north at 423 meters in 6.8 seconds, what is its velocity?

Without comments it is extremely difficult to add to others statements. The velocity MUST include a direction. As NCS has done. If the projectile lands at this distance then there is no vertical displacement so the velocity over this time has NO vertical component. It is horizontal, 423/6.8 = 62 m/s North.

Idk if by north you mean up. If not, it should be irrelevant. If you mean displaced 423 meters horizontally, then its horizontal velocity is 62.2 m/s given the air resistance is negligible.

If you’re saying the projectile displaced 423 meters vertically, then its final velocity is 95.5 m/s and it’ll either be in the first or second half of its projectile motion. This is ignoring air resistance.

the horizontal component of the velocity is 423/6.8 m/s

the vertical component and total velocity are unknown.
