Two long, perpendicular conveyor belts lie in the horizontal plane of a factory floor. Belt 1 moves due east (\(+x\)-direction) at constant speed \(v_0\) relative to the floor. Belt 2 moves due north (\(+y\)-direction) at constant speed \(2v_0\) relative to the floor. A motorized robotic module \(M\) moves across Belt 1. A sensor mounted on Belt 2 tracks module \(M\) and measures its velocity relative to Belt 2 to be directed due west (\(-x\)-direction) with magnitude \(v_0\). Which of the following expressions correctly gives the speed of module \(M\) relative to the factory floor, \(v_{M/F}\), and the speed of module \(M\) relative to Belt 1, \(v_{M/1}\)?
