# Sonic boom

Classical Mechanics Level 2

A jet plane is flying at a height of $$5000\sqrt{3}$$m and a constant velocity of $$2v$$ as above. When a person at point P on the ground hears the sonic boom, the jet plane is at point B. What is the distance between point A and B? (The velocity of sound in the air is $$v$$ irrespective of height. We ignore the size of the jet plane.)
