# What is Newton's formula for projectile motion?

Dec 5, 2014

His formula is just just an equation of a parabola

if A is the angle at which the projectile is fired and V is the velocity and t is the time, g is the acceleration due to gravity

then, the equation is

y = $- g {x}^{2} / \left(2 {V}^{2} C o {s}^{2} A\right) + x \tan A$

play around this, set y to zero you get x as the maximum range.

you can solve for the vertex, and you will get the max. height reach at a horizontal distance covered.....
