A submarine dives from rest a 100-m distance beneath the surface of an ocean. Initially, the submarine moves at a constant rate of 0.3 m/s2 until reaches a speed of 4 m/s and then lowers at a constant speed. The density of salt water is 1030 kg/m3. The submarine has a hatch with an area of 2 m2 located on the top of the submarineās body.
a. How much time does it take for the submarine to move down 100 m?
b. Calculate the gauge pressure applied on the submarine at the depth of 100
m.
c. Calculate the absolute pressure applied on the submarine at the depth of
100.
d. How much force is required in order to open the hatch from the inside of
the submarine?
answer this step-by-step, please.
