what is the equation for horizontal velocity?

Question

anonymous · Answer

Are we talking about projectile motion where we neglect air-resistance and no forces act in the horizontal direction? Unless we narrow it down, there are infinite number of equations.

anonymous · Answer

yes neglect air resistance i am looking for a simple one using time in air, horizontal distance, and vertical distance

anonymous · Answer

Okay. If we launch an object at some initial velocity, we can use the equations of projectile motion. Since there is no acceleration in the horizontal direction, and gravity is the only acceleration in the vertical direction. Take a look here for the equations that govern projectile motion: http://en.wikipedia.org/wiki/Projectile_motion
