A cruise missile with an ideal ramjet engine is flying at Mach 4.0 at an altitude where the ambient temperature is $100 \mathrm{~K}$. Considerratio of specific heats $=1.4$ and specific gas constant $\mathrm{R}=287 \mathrm{~J} / \mathrm{kgK}$. If the stagnation temperature in the combustion chamber is equal to $2310 K,$ the speed of the exhaust gases $(\mathrm{in} \mathrm{m} / \mathrm{s})$ is_______________________
