During the transition from the run up to take-off, the athlete begins to gradually lowering his center of body mass or gravity center, which, by decreasing the take-off height, prepares the optimal launching angle, around 20-22[degrees], (Ashby & Heegaard, 2002).
A properly relationship between horizontal and vertical vectors will generate a third important factor - the resulted vector - inducing the optimal launching angle, thus the jumper reaching a high level of velocity, (Rebutini et al., 2016).
This study starts with the hypothesis that there is a direct connection between the launching angle and the angle of entry of the ball in the basket, connection which can be mathematically demonstrated.
Demonstration of the connection between the launching angle and the angle of entry of the ball in the basket
The connection between the launching angle and the angle of entry of the ball in the basket can be obtained through the compose laws of speed in a uniform gravitational field (relation 2)
By working out relations 1 and 2 we can obtain the dependence relation between the launching angle and the angle of entry of the ball in the basket (relation 3).
