Re: Springs?? (10 lbs. at 22 ft/s)

If you figure that the mass of the ball is ~3.5 kg and you want to shoot it to a height of 2.5 meters (a little over 8 feet) then:

(3.5 kg)*(9.8 m/s^2)*(2.5 M) ~ 86 Joules

This is assuming that the horizontal componant of the balls velocity comes from your moving robot.
