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. 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.
