4.2. A gun fires a bullet verticalls, where g=3.71m/s2=12.2ft/s2. the gun at a velocity of 2500ft/s. Aird. The bullet has a mass of 0.025lbm and leaves (a) How much kinetic energy /s. Air resistance is negligible (for this problem only). (b) How high will the bullet does the bullet possess when it leaves the gun? (c) At its highest point, how much potential energy will it have relative to the gun barrel
