Let
Code:
d = horizontal distance (in feet) from launch point to hoop

h = vertical height (in feet) of hoop above the launch point

a = angle of launch (radians) above the horizontal

v = initial speed of ball (in ft/sec) as it leaves the launcher
Then the no-drag, no magnus formula for speed is:
Code:
v = 4*d/(cos(a)*sqrt(d*tan(a)-h))
