The Motion of NASCAR
The Talladega Motor Speedway 2.66 Miles round trip
The Talladega Motor Speedway Data Collection 2.66 Miles = 4256 m 1 mile = 1600 m Average time for a single lap is 53.5 seconds (data from Talladega race February 2011) Average Velocity 4256 m = 79.6 m/s 53.5 s
How do we achieve this speed and still keep the car on the track? Average Velocity 4256 m = 79.6 m/s 53.5 s
What Force is needed to make an object travel in the path of a circle? Centripetal Force
So in order for a race car to go around the track something must provide the centripetal force… Friction!
Force of Friction = 1550 (79.6) 2 = 29290 N 335.3 We have a problem! 29290 N = 2960 kg Our car only has a mass of 1550 kg
How do we fix the problem? 29290 N = 2960 kg Our car only has a mass of 1550 kg Bank the track!
Talladegas Curves are banked at 33 degrees
The more banking, the less centripetal force is needed…. the faster it can go!
