There are several problems on ballistic that illustrate in a straightforward manner the application of Newton’s equations to parabolic motion. Think for example that a projectile is launched in front of a fence of height \(h\) located at a distance \(L\) from the place of firing.
Here is an example of the application of Newton’s second law of motion to a ballistic problem. The problem we want to consider is calculating the critical angle \(\theta_c\) of firing a projectile from the ground toward a high place (of height \(h\)), located at a distance \(L\) in front of the place of firing.
