Ashock wave is moving at a mach number of 3 into undisturbed air (t=20ºc and p=101.3 kpa). what are the velocity and stagnation temperature (with respect to a stationary observer) of the air after the passage of the shock wave? also find the static pressure and temperature and stagnation pressure (relative to a stationary observer) after the shock passage.
