So I'm trying to get ahead of the class for next year and i've started reading this physics book, now I've come along to work and i'm slightly confused on whats happening.(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

A force of 10 Newtons to the north-east acts on an object as it moves 25 metres to the south-east. What is the work done by the force?

2. Relevant equations

W = F*d

3. The attempt at a solution

I've tryed to use trigonometry to solve this, but i don't think i done it correct as the answer is 0J

cos = A/h

a = 25

25/cos45 = h

h * 10 = W

I get around 353J which is completely wrong.

If anyone could help me out, it'd be great.
