1. Homework Statement
A plane passes from 900 meters over my head. I hear the shockwave after 2.2 seconds. At what speed in Mach is the plane flying ? Speed of sound = 331. 4 m/s
2. Homework Equations
Machs = speed of plane / speed of sound
3. The Attempt at a Solution
I don't have any clue where to go with this, maybe find the angle of the cone ? it gave me an angle of like .14 degrees and an impossible answer of the plane speed... dah
Thanks in advance
