Suppose a 100m diameter stony (p= 3 g/cm^3) meteroid impacts the Earth with a speed of 20km/s. Assume all kinetic energy goes into the creation of an atmospheric blast wave.
Estimate how far from the site of impact the resulting shock front propagates before its speed is equal to the sound speed of the ambient atmosphere. (Assume the ambient atmosphere, through which the blast wave propogates, has mass density of 1.225x10^-3 g/cm^3 and temperature of 60 degrees F (or 288 Kelvin)).
