a car of mass 1400 kg is parked on a very slippery hillside (fig.). to keep it from sliding down the hill, the owner attaches a cable. (a) sketch all the forces on the car. include coordinate axes in your sketch. (b) determine the components of all the forces on the car along the coordinate axes. (c) write the conditions for static equilibrium along your two coordinate directions. (d) if there is no frictional force between the road and the tires, what is the tension in the cable?
