Question

The gauge pressure in each of the four tires of an automobile is 240 kPa .

If each tire has a "footprint" of 150 cm2 (area touching the ground), determine the mass of the car.

Express your answer to two significant figures and include the appropriate units.

Answer 1

Answer #1

linen P = 240 kPa = 2.40X105 Pa A = 150 cm² = 150x104 m2 force on each tire F = Pg A - F= 2.400105 x 150x104 F= 3600 N By bel
