I MADE A MISTAKE! Yes, first one this year ...unless you count...
When I found the speed at the top of the tire to be 3V ( 2V wheel Speed at
the top [plus the wind speed) I had my head somewhere esle (like up
my...well you figure it out). Speed at the top is only 2 V. Which makes the
required vehicle speed evem higher to get to a sonic boom... so, about about
760 mph divided by 2 is about 380 mph.
wonder how many mistakes I will make today. I think I will just go back to
bed...
mayf, far oof planet in Pahrump
