Homework Statement
A jet fighter in level flight passes directly overhead at a speed corresponding to Mach number 1.29. The sonic boom is heard by you on the ground 11.9 s later. What is the altitude of the plane? Assume (unrealistically) the speed of sound does not change with altitude.
Homework Equations
Mach = vsource / vsound
The Attempt at a Solution
M = vsource / vsound
1.29 = vsource / 343
vsource = 442.47 m/s
d = vt
d = (442.47 m/s)(11.9 s)
d = 5265.393m = 5.265 km
the answer above was wrong, any help is appreciated!
