In an experiment to determine the speed of sound, two observers, A and B, were stationed 5.00 km apart. Each was equipped with a gun and a stopwatch. Observer-A heard the report of B’s gun 15.5 s after seeing its flash. Later, A fired his gun and B heard the report 14.5 s after seeing the flash. Determine the speed of sound and the component of the speed of the wind along the line joining A to B.
