The Walther PPK, a sleek and easily concealable handgun due to its short length and low (unloaded) mass of mPPK = 480g. Its magazine holds 9 rounds that have a mass mround = 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 ; one grain=1gr=64.79891mg.
What are.....
a) the recoil velocity
b) the recoil energy
c) the recoil force of the first fired round?
d) How do the recoil properties change as you keep emptying your clip? For this last question we are only looking for a verbal answer motivated by “qualitatively” discussing the symbolic equations used before.
