The four tires of an automobile are infalted 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 autmobile.
Is 1.92*10^4 right? If so, what are the units.
Units: A Pascal is a newton/meter^2. Yes, it is right. Normally we would use the unit kilopascal here, but it is ok.
