Your expert marksman skills are well known around the country. as a result you are recruited by the cia and immediately assigned to a joint operation with the british mi6 (foreign intelligence) for deployment in northern africa. while you master faking a north african accent, bringing with you your favourite smith& wesson 500 would likely expose you as a spy. her majesty’s top agent, codename 007, therefore lends you his favourite silenced walther ppk (german for "polizeipistole kurz" or in plain english just "police pistol short"), a sleek and easily concealable handgun due to its short length and low (unloaded) mass of mppk = 480g. its magazine holds 9 cartridges that have a mass mcart = 7.83g each. using a standard 7.65×17mm browning .32 acp ammunition with a bullet mass mbullet = 60gr the walther ppk achieves a muzzle velocity of vmuzzle = 335m s ; 1gr=64.79891mg. a) what are the recoil velocity, b) the recoil energy, and c) the recoil force of the first fired round? as a well trained citadel soldier you know that one shot will not be enough and you anticipate to empty the full clip (likely more than once) during your mission. d) how do the recoil properties change as you keep emptying your clip? for this last question we are looking for a verbal answer motivated by "qualitatively" discussing the symbolic equations used before.
