Great story in the news and on the web today. CART (Championship Auto Racing
Teams) drivers refused to race in the Firestone Firehawk 600 at the Texas Motor
Speedway because of a new track. The track is banked at 24 degrees and the cars
travel over 236 mph. During practice sessions they got up to 236.9 mph. See
www.cart.com and click on the second story. The San Jose Mercury News has a
longer article and includes a graphic showing the Texas Motorway bank a 24
degrees, the Michigan speedway at 18 degrees, and the Indianapolic Motor
Speedway at 9 degrees.
Great warm-up exercise for the class to calculate and compare the "g" forces on
the three tracks.
