A pinball machine uses a spring launcher that is compressed 6.4 cm to launch a ball up a 14 degree ramp. Assume that the pinball is a solid uniform sphere of radius r = 1.0cm and mass m = 29 g.

If it is rolling without slipping at a speed of 3.3 m/s when it leaves the launcher, what is the spring constant of the spring launcher?
