Problem 4.14

A particular race car can cover a quarter-mile track(402 m) in 6.40 s starting from a standstill. Assuming theacceleration is constant, how many gs does the driverexperience? If the combined mass of the driver and race car is535 kg, what horizontal force must the road exert on the tires?
