Assume that a car travelling on horizontal straight road with an accelration of a 5 `ms^(-2)` has all its windows rolled up and all air vents closed. Length of the car is L=3.0m. By considering a horizontal tube of air that extends from the windshield to th rear surface, and applying Newton's Law on it, calculate the difference in pressure of air at the rear and front of the car. How does this pressure compare with the atmospheric pressure? Density of air `rho=1.2kgm^(-3)`

Answer

`18Nm^(-2)`
