Homework Help: PHYSICS

Posted by Gabby on Saturday, March 19, 2011 at 10:16pm.

If Superman is flying at mach 4, 1 km above the ground and yells "Hey! Finish your test!" from directly overhead, what does it sound like when you finally hear him? Superman travels slower than light and therefore you don't hear him until he is 4.1231 kilometers away.
Speed of Sound = 340 m/s

How do I even answer this?
