Several experiments are carried out during which a ball, which first rolls on a table, reaches the end of the table and begins a parabolic movement. Each time, the ball will be 2,9 m above the ground when it leaves the table.   the ball rolls on the table which is inclined at an angle of 23° to the horizontal, as shown in the image. The moment it leaves the table, its speed has reaches a module of 9m/s. What is the range of the ball from the point where it leaves the table?
