1000-mph Car Planned

Smivs notes a BBC report on a British team planning a 1000-mph record-breaking car. The previous land-speed record broke the sound barrier. The proposed vehicle will get from 0 to 1,050 mph in 40 seconds. "RAF pilot Andy Green made history in 1997 when he drove the Thrust SSC jet-powered vehicle at 763 mph (1,228 km/h). Now he intends to get behind the wheel of a car that is capable of reaching 1,000 mph (1,610 km/h). Known as Bloodhound, the new car will be powered by a rocket bolted to a Typhoon-Eurofighter jet engine. The team-members have been working on the concept for the past 18 months and expect to be ready to make their new record attempt in 2011."

1000 mph speed, 100 gallons per mile efficiency

I can't help it but giggle when these speed-record setting land vehicules are referred to as "cars" when they're basically rockets with wheels and a seat.

Your at 4x the correct g. The rate of rotation is based off of the speed of the car relative to the speed of the ground. The top of the tire is moving at twice the speed of the car relative to the ground but the bottom is not moving relative to the ground. However, it's all 1x the speed of the car relative the center of the tire. Which is the frame of reference you need to calculate the centripetal force. PS: It's also a good idea to note only the outside edge of the tire is under that much g loading as to move to the center of the tire the g forces drop to zero. (It's still an insane speed to rotate a tire.)
