* Aim. From a physical point of view, in a basketball, when a player make a basketball throw, there are several factors that interfere that determine the ball's trajectory. The most important factors are: the weight of the ball, the speed at which the ball is launched by the player and the angle at which it is launched. There are also other factors that are not so important, such as air resistance, as well as the so-called rotational effect (Magnus effect), which is due to all the interaction

In this article we will treat the perfect throw to the basket in which the player attempts to execute a distance throw, outside the half-circle of 6.75 meters, so that the ball penetrates the basket without touching the ring. Conclusions. Some models and assumptions allow us to calculate an approximate optimal angle, which would fall in the vicinity of 49°, for throwing speeds around a minimum of 8.2 m/s. When the throw angle drops noticeably below this value, the throw speed increases and the angle of entry in the basket decreases, lessening the chances of marking. On the other hand, when the throw angle increases noticeably, the throwing speed increases similarly, and the flight time is the same, which reduces the chances of the ball entering the basket. The more the player prints the ball at a higher angular speed, the more it has to print a lower initial speed, or to throw at higher angles (the input angles are even higher), both improving less chances of success.
