If a TOF mass spectrometer needs to scan an m/z of 600, what is the speed of this ion if it is accelerated through 4000 volts?  How long will this ion (at the speed calculated) take to drift 2.00 m through the spectrometer?  How many mass spectra can be taken each second if a new cycle begins each time this ion reaches the detector?
