Eric...for some reason, the figure of about 9,000 mph sticks in my head as the point of retardation. I don't know where to resource that figure to see if its right or not...but I think its close. geozay
>>>>George jut brought up a good point and I have a question. The speed of sound is about 760 MPH. What is the speed at which a meteoroid extinguishes and is no longer incandescent?>> I believe its in the neighborhood of 7,000 mph. If its a small meteoroid, it will extinguish way too high for a sonic boom to reach the ground.
