An electric failure left a submarine submerged in the ocean at a depth of 30 m. The crew decide to escape by opening a hatch at the bottom of the submarine. The hatch has 1.00 m of diameter and a mass of 30.6 kg. If the pressure inside the submarine is the atmospheric pressure, what force is needed to open the hatch?
