1. The problem statement, all variables and given/known data A plane is traveling at Mach 2.5. An observer on the ground hears the sonic boom 1.0min after the plane passes directly overhead. What is the plane's altitude? Ignore the change in the speed of sound with the altitude. 2. Relevant equations v=d/t 1/T= f 3. The attempt at a solution Hey guys I am having trouble with this problem. I tried changing mach to velocity = 857.5 m/s and I tried 850 m/s Time 60 seconds I've tried v x t = d My answers are 51000 m and 51450 m I have no idea where I am going wrong. I also tried to find the wavelength and using that as an answer but it was wrong also.
