Homework Statement
The gauge pressure in each of the four tires of an automobile is 240 kPa. If each tire has a "footprint" of 220 cm2, estimate the mass of the car.
Homework Equations
F= ma ?
W1 = P1A1 ?
The Attempt at a Solution
total weight = W1+W2+W3+W4 = P(A1+A2+A3+A4) <------- since all tires have same surface area and same pressure.
240pka(2.2m^3 x 4) = 2112 kg??
dont think i did that right
