Ball at the wall
context

In a ball-at-the-wall game, children in the schoolyard must throw balls at the school wall to reach lines placed at certain heights. You want to predict how high the ball will hit the wall based on the parameters of the throw.

Constraints and information

The children are all placed behind a line drawn on the floor, at a known horizontal distance ? from the wall;
The initial height at which the ball leaves the child's hand is known;
The speed and angle of the throw are known;


Modelization

Creates a model to determine how high the ball will hit the wall based on the children's distance from the wall and the height, speed and angle of the ball as it leaves the child's hand .

Then test your model with the following parameters

Distance between the wall and the child: 3.9m;

Height of the ball when it leaves the child's hand: 1.05m;

Throw Speed: 14.1m/s;

Throw angle: 51∘
