A rescue cable attached to a helicopter weighs 2 lb/ft. A 160-lb man grabs the end of the rope and is pulled from the ocean into the helicopter. How much work is done in lifting the man if the helicopter is 40 ft above the water?

OpenStudy (anonymous):

can i get some help?

OpenStudy (dbzfan836):

Hmm, I can help you

OpenStudy (anonymous):

YAY! thank you!

OpenStudy (anonymous):

i dont have anything to give tho. sorry :(

OpenStudy (dbzfan836):

If I am correct, work is force by distance, or w=fd

OpenStudy (dbzfan836):

force is like the wieght he lifts, which is his wieght and the ropes, or 162 lb. per foot

OpenStudy (anonymous):

ok

OpenStudy (dbzfan836):

so 162*40= what?

OpenStudy (anonymous):

so 162x40

OpenStudy (anonymous):

6480

OpenStudy (dbzfan836):

that means the total force, if I am correct, is 6,480 Newtons

OpenStudy (dbzfan836):

I would like someone to make sure

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

so w = 6480d

OpenStudy (dbzfan836):

Well, not really. w is joule, or newton-meter

OpenStudy (dbzfan836):

say it is 6,480 j

OpenStudy (dbzfan836):

@ganeshie8

OpenStudy (anonymous):

but on the paper it says w= 8000

OpenStudy (dbzfan836):

well I need another person to help

OpenStudy (dbzfan836):

And ps Nobody else is helping you because this is a physics question

OpenStudy (anonymous):

o but im in calculus 2 this was a calculus 2 question

OpenStudy (dbzfan836):

hmm well Its kinda both

OpenStudy (dbzfan836):

work and force are both used in physics. work and distance calculate force.

OpenStudy (dbzfan836):

Those are from physics

OpenStudy (anonymous):

o ok

OpenStudy (dbzfan836):

Ask it in physics anyway. you will get more help

OpenStudy (anonymous):

ok thanks

OpenStudy (dbzfan836):

You can get it from someone more experienced. I am in 9th yet I am not even 13

OpenStudy (dbzfan836):

Ill be in physics

OpenStudy (anonymous):

O ok! thanks for the help!
