Answer 2

\[\huge \text{W}=Fd \cos(\theta)\]

Answer 3

The cosine is involved because we need to find the component that is parallel to the force being applied.

Answer 4

so we need to convert LB TO KG?

Answer 5

and the ft too?

Answer 6

Hmm, I would probably convert it.

Answer 7

ok, lets move on then...
