This website show the backspin of the ball. It also for the backboard when you hit it in a 50 degree. If a 6 foot person is shooting the hoop than he would be in a 50 degree because that the best for a 6 foot tall person.

This helps me because playing in a game helps to know what would it be if you are 5 foot than they will have different angle and their shooting. The backboard is useful for the basketball to shoot.
