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 what's happening.
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?
W = F*d
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.
