On aircraft carriers, catapults are used to accelerate jet aircraft to flight speeds in a short distance. One such catapult takes a 18,500-kg jet from 0 to 68 m/s in 2.9 s. (Assume the catapult acts in the positive horizontal direction. Indicate the direction with the sign of your answer where appropriate.)

(a) What is the acceleration of the jet in m/s2? 23.45 m/s2

What is the acceleration of the jet in g's? g

(b) How far does the jet travel while it is accelerating? m

(c) How large is the force that the catapult must exert on the jet? N

    An acceleration voltage of 30.0 kV is used to accelerate ions into the 1.54 m flight tube of a time‑of‑flight (TOF) mass spectrometer. The frequency at which spectra can be recorded is dependent on how long it takes the slowest ion to travel from the source to the detector. If you wish to scan up to ?/?m/z 6801 at what frequency (spectra/s) could spectra be recorded if a new spectrum begins each time the slowest ion reaches the detector? frequency:................spectra/s
