it would depend on the object's weight and other variables. i have, however, done a lot of research on the Titanic, and i may be able to answer your example: "whatspeed was Titanic doing when it hit the bottom?"
I doubt that there were any air pockets in the bow section... it went down first, and slowly at that. the water would've pushed the air out as it flooded and would've been just about empty of air when it submerged. The bow section hit the ocean's bottom at a faster speed than the titanic could sail at full steam... so fast, that the decks compressed and support collumns can be seen in an acute bend, like this: <
...and the bow is under the mud right up 'til just below the anchors on both sides. also, the air would've been pushed out of the ship before it reached a quater of the way down... the pressure woul've been way too much... hence why the stern is all messed up.
Getting back to the bow section, 22knots per hour is about 40.744km/hr. and the Titanic's top speed. if the titanic's bow lays at about 3.821km below the surface, then it would've taken about 10 minutes for the bow to hit the bottom at full steam, less time if it was travelling at a greater speed.
i'm not sure about the stern. it was in thousands of pieces by the time it hit the bottom...
Also, it takes the submersibals 2 hours to get to the bottom because they weigh nothing compared the titanic, which was 46,000 tonnes, and the sub is full of air.
well, i hope this helps. it's been a while, but i think these numbers are accurate. the depth and weight are, i'm not sure with the speed. it's pretty accurate though.

Anything denses than water will sink, as does anything denser than air will fall.The greater the difference in density will result in a faster fall/sink. Terminal velocity, is not always reached, it depends on shape, air resistence, so object like the titanic would be effected by this too. With water, it would take longer to reach a terminal velocity due to the liquid being thicker, so you might reach the bottom before it is reached. Its terminal velocity is much lower than that of air.

I don't know how fast Titanic was travelling when it hit the bottom of the sea bed. If you know the depth of the sea where it sank, the mass of Titanic, and its shape - you'd probably be able to make a good estimate, assuming that it was completely flooded (no significant amount of air).
There is definitely a terminal velocity in water as there is in air. The velocity is lower and it will be reached in a shorter distance.

When for example a ship sinks, any trapped air pockets will be compressed by pressure thus the bouyancy effect will have no effect, the deeper the vessel sinks the greater the pressure of water. When Titanic sank she would have impacted the ocean floor at about 50 mph causing massive structural collapse, combine this with the water pressure it would soon be squashed flat.
Ships sinking in shallow waters say 30 to 40 M. are capable of
being salvaged if not too damaged by collision etc.

If there is a terminal velocity, then that velocity will depend on the object, just as it does in air. More buoyant objects will sink more slowly than less buoyant ones... or even float!

It depends on the relative serface area and weight of the object but i can tell you that any object will sink slower in salt water than in fresh water becasue the salt in salt water raises the density of the water so the object has more resistance when sinkin through it.

Also depends on the salinity of the sea, things sink far slower in the dead sea for example, as a person can't sink there, only float.

An object sinks into water or sea depending upon its weight.
The heavier the object, the faster it sinks. This is why an iron sinks faster than paper.

I think it depends on the size and how heavy the object is...As for titanic,altho it was heavy it did take alot longer to sink,yet once it started to go down it went down with great force resulting in it being smashed to smitherines.

u can get it froma 6th standard book.i think so it depends upon the mass of an object i.e.the weight of an object
