Fill in with measurements:
Drag force = (1/2) * 1.204 kg/m^3 * (12.8016 m/s)^2 * 0.4 * 0.638 m^2 = 25.192 Newtons (approx. 5.337 pounds).
So yeah, that's gonna be a bit tough. Mathematically, you could figure out how much force is needed to have the ball travel at a speed without regarding drag, then just tack the drag force onto that. Making something to force a ball to go at that speed will be hard, though. |
I haven't really done any math, but putting a wheel directly on a CIM spins terrifyingly fast, and has a sound to match.
