a submarine rescue chamber has a mass of 8200kg and safely descencds at a constant velocity of 10cm/s [down]. If g=9.81m/s2, what is the upward force exerted by the cable and water on the chamber?

OpenStudy (anonymous):

@experimentX ?

OpenStudy (experimentx):

8200x9.8N minus upthrust. any other information give??

OpenStudy (experimentx):

I mean you know the answer??

OpenStudy (anonymous):

nope, only that given.

OpenStudy (anonymous):

the asnwer is 8.0x10^4 N [up]

OpenStudy (anonymous):

you got the answer, but then what do you go with the 10cm/s #?

OpenStudy (experimentx):

force produces acceleration .... there is no acceleration, constant velocity is irrelevant,

OpenStudy (anonymous):

okay, thank you so much. so just 8200*9.81 then !

OpenStudy (experimentx):

yes ... since no information about upthrust is given.

OpenStudy (anonymous):

yuppp, thats the answer in the textbook, thank you once again !
