The weight of a car is 8400N Each tire supports a weight of 2100N The pressure exerted by each tire on the road is 20 Ncm How do you calculate the area of each tire in contact with the road?

Each tire supports 2100 N, and the pressure exerted by each tire is 20 N per centimeter2, so Pressure = Force / Area Pressure = 20 N per centimeter2 Force = 2100 N rearranging the equation for Area Area = Force / Pressure Area = 2100 / 20 = 105 centimeter2 So each tire has 105 cm2 touching the road.
