    Is the Faulty Velocity Equation for Projectile Launch Valid?

    This was a simple question. I just wanted to know if anyone had ever seen this equation before. It seems too simple to calculate velocity especially when other equations have one calculating both horizontal and vertical components to arrive at an answer. Maybe you can answer one last question...

    Is the Faulty Velocity Equation for Projectile Launch Valid?

    How would I know for sure? I'd have to be able to measure the time and the time measurement would be so small that I'd not be able to accurately measure it. I guess I could quesstimate it, but it would be under a second, so pretty hard to measure accurately.

    Is the Faulty Velocity Equation for Projectile Launch Valid?

    The answer (V) is expressed in m/s. meters/second

    Is the Faulty Velocity Equation for Projectile Launch Valid?

    I guess I'm not understanding your question. g is the GA constant of -9.8 meter/second squared and h is the height of the table. Do you want a measurement for h? One measurement I have for this is h= -1.25 meters and D= 2.4 meters. That's all the information that seems to be required to...

    Is the Faulty Velocity Equation for Projectile Launch Valid?

    I have seen this equation used to calculate the velocity of a projectile being launched off a table top. Where D=horizontal distance travelled, h=table height, and g=gravitational acceleration. Nowhere else can I find a calculation of velocity based on only two distances and GA. Everything I...
