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

Unable to determine, due to lack of vector data.

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.

423m [N] / 6.8s = 62 m/s [N]

as your velocity has both magnitude and direction.

velocity = distance/time = 423 m / 6.8 s = 62.2 m/s

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

the vertical component and total velocity are unknown.

423/6.8. Do the math.
