Is there an equation to see how high thrown objects go?
Yes there is. It includes the force on the object, the weight of the object, the atmosphere, wind and many other things.
The height the javelin reaches can be estimated if you know the amount of time the javelin is in the air:
![]()
where= acceleration due to gravity (32.2 ft/s^2, or 9.8 m/s^2) and
= time from release to hitting the ground. This formula assumes that the maximum height attained is "large" compared to the height above the ground when the javelin is released.
Alternatively if you know the distance the javelin is thrown and assume that the thrower launched the javelin at precisely 45 degrees from horizontal it's possible to make an estimate, but that assumption may be unrealistic. Ignoring the effects of air resistance the max height woud be 1/4 of the distance of the throw.
If we don't know the time in the air, can we use this formula?:
h = (0.5*v^2)/g
