Vacuum trajectory of a projectile for different launch angles. Launch speed is the same for all angles, 50 m/s, and "g" is 10 m/s 2. To hit a target at range x and altitude y when fired from (0,0) and with initial speed v the required angle(s) of launch θ are:
A launch angle of 45 degrees displaces the projectile the farthest horizontally. This is due to the nature of right triangles. Additionally, from the equation for the range :

English: Trajectories of projectiles launched at different elevation angles and a speed of 10 m/s. A vacuum and a uniform downward gravity field of 10 m/s² is assumed. t = time from launch, T = time of flight, R = range and H = highest point of trajectory (indicated by arrows). The points are at 0.05 s intervals.
The authors consider the effects of gravity, drag and the Magnus Effect using Newton’s laws of motion to calculate the position of the ball at different points in time, allowing them to model the trajectory of the ball in 3 dimensions. Several examples of lift coefficient and launch angle are given and two-dimensional trajectories are graphed ...

Holding one end in both hands, palms facing the floor, pull straight back with your elbows at a 90-degree angle. From that position, raise your forearms to create another 90-degree angle. Then ...
To find the angle giving the maximum height for a given speed calculate the derivative of the maximum height = / with respect to , that is = / which is zero when = / =. So the maximum height H m a x = v 2 2 g {\displaystyle H_{\mathrm {max} }={v^{2} \over 2g}} is obtained when the projectile is fired straight up.
