An electrical short cuts off all power to a submersible diving vehicle when it is a distance of 29 m below the surface of the ocean. The crew must push out a hatch of area 0.950 m2 and weight 390 N to escape.
If the pressure inside is 1.0atm, what downward force must they exert on the hatch to open it?
