Question

On August 12, 2000, the Russian submarine Kursk sank to the bottom of the sea, 350 feet below the surface. The density of water is 62.4 lb/ft^3.

(a) Find the water pressure in pounds per square foot at the depth of the Kursk.


(b) Find the force on a 5 foot square metal sheet held horizontally at the depth of the Kursk.

Find the force on a 5 foot square metal sheet held vertically at the depth of the Kursk. (The bottom of the sheet is at a depth of 350 feet.)

Answer 1

pressure = denstiy*gravity*depth

Answer 2

Pressure =Force/Area
Reaarange this formula to find the force.
