A force of 60 pounds is exerted along a rope attached to a crate at an angle of 30o above the horizontal. The crate is moved 29 feet. How much work has been accomplished? Round answer to one decimal place.

Question

anonymous · Answer

60 lbs = 266.8 N
28 ft = 8.84 m
the horizontal force would be 266.8cos(30)
so 

W = F * d
W = 266.8cos(30) * 8.84
W = 363.80 J

oh..they dont' want in SI units...
that's silly..

doing the exact same thing as i did up there
but don't convert, notice they're using the same units given in the question, so i guess it's easier.

but do the exact same thing and you'll get E. 1506.88
