Question

The four tires of an automobile are inflated to an absolute pressure of 2.0*10^5 Pa. Each tire has an area of 0.024m^2 in contact with the ground. Determine the weight of the automobile.

Pressure*area= force. There are four tires.

Answer 1

19200

Answer 2

pressure = force / area
force = pressure * area
multiply by four because there are four tires so
force = pressure * area * 4
force = (2.0*10^5 Pa) * (0.024m^2) * 4
force (weight) = 19200N or 1.9*10^4N
