W=Fdcosθ
plug in your info.
btw, this is a physics question

and btw, your actual calculator answer isn't there, but an estimate is there.

@kianataylor u got it?

anonymous · Answer

work is always calculated in the direction of motion so we have to consider that part of force that is responsible for the motion i.e its cosine part|dw:1366706171071:dw|
so work done =force*distance*cosine of angle between them :)
