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 51.3milesper hour? (The car would need rocket boosters!)

4: Suppose the mass of a
rocket just as it runs out of fuel is 75550-kg, and its exhaust
speed is 2.7 × 103 m/s.
Calculate
the maximum rate, in kilograms per second, at which the rocket can
expel gases, if its acceleration cannot exceed seven times that of
the gravitational acceleration on the surface of the Earth. Assume
the gravitational force on the rocket is negligible.
