Trajectory equation means the locus of the motion of anybody. From this
equation you can get the information of the motion of that body. A projectile is an object that is given an initial velocity, and is
acted on by gravity. The path the object follows is called its
trajectory. The trajectory has horizontal (x) and vertical (y) position
components.
You can use the formula:
y= xtan(θ)− ((g∗x2)/(2v2cos2(θ))wherein:
y = vertical position (m)
x = horizontal position (m)
v0 = initial velocity (combined
components, m/s)
g = acceleration due to gravity
(9.80 m/s2)
