    Ok, so that means 1.67 revolution per second. If I substitute that into the equation f =fo(1/ ((V +/- Vsource)/V)) f+ = 600(1/ ((1.67 + 10.4719)/1.67)) = 82.39 f- = 600(1/ ((1.67 - 10.4719)/1.67)) = -113.60 Is that right?

    Oh! but how do we find the velocity (V) ? It's 100 rpm, so do we convert that to revolution per second? Thanks!
