Answer

The mass of the car is 1900 kg

Work Step by Step

We can find the upward force exerted on the car. $F = 4\times P~A$ $F = (4)(2.4\times 10^5~N/m^2)(190\times 10^{-4}~m^2)$ $F = 18,240~N$ We can use this force to find the mass of the car. $Mg = F$ $M = \frac{F}{g}$ $M = \frac{18,240~N}{9.80~m/s^2}$ $M = 1900~kg$ The mass of the car is 1900 kg.
