Problem 3 (10 Points) Lumped thermal capacitance model 3. A spherical lead bullet of 6-mm diameter is moving at a Mach number of 3. The resulting shock wave heats the air around the bullet to 700 K, and the average convection coefficient for heat transfer is 500 W/m K. If the bullet leaves the barrel at 300 K and the time of flight is 0.4 s, what is the surface temperature upon impact? (k = 35.3 W/mK, c= 129 J/kg K, lead lead lead = 11,400 kg/m³).
