SUMMARY
The race car covers a quarter-mile track (402 m) in 6.27 seconds with constant acceleration, resulting in an acceleration of 20.45 m/s². This translates to an experience of approximately 2.09 g's for the driver, as one g equals 9.8 m/s². The initial confusion stemmed from the incorrect application of the formula F=ma instead of the kinematic equation x = x₀ + vt + 1/2at². The discussion highlights the importance of using the correct formulas for solving physics problems related to motion.
PREREQUISITES
