Problem
Jachym was launching fireworks. We can imagine it as a beacon, that is at some point shot straight up with velocity v, and explodes after a certain delay. Jachym was standing a distance x from the launch site when he heard the launch of the fireworks. After a delay t1 he saw the explosion and after another delay t2 he heard the explosion. Calculate the velocity v.
