Aprojectile in flight canties with it a more or less conical-shaped shock front. from physical reasoning it appears that at great distance from the projectile this shock wave becomes truly conical and changes in vclocity and density across the shock becomes vanishingly small. photographs of a bullet in light show that at a great distance from the bullet the lotal included angle of the conç is 50,30°. the pressure and lymperature of the undisturbed air ir 100.801 kpa and 22.78°c. respectively. calculate thç velocity of the bullet, and the mach number of the bullcl. relative lu the undisturbed air.
