The average person passes out at an acceleration of 7g (that is, seven times the gravitational acceleration on Earth). Suppose a car is designed to accelerate at this rate. How much time would be required for the car to accelerate from rest to 66.2 miles per hour? (The car would need rocket boosters!) Answer is in seconds!
