Consider a heavy car submerged in water in a lake with a flat bottom. The driver’s side door of the car is 1.1 m high and 0.9 m wide, and the top edge of the door is 10 m below the water surface. Determine the net force acting on the door (normal to its surface) and the location of the pressure center if (a) the car is well–sealed and it contains air at atmospheric pressure and (b) the car is filled with water.

Height of the door b = 1.1 m
Width of the door a = 0.9 m
Distance from the edge of the car and the surface of water s = 10 m
