Vector (physics) Homework Help
I missed two days of class because of a doctor's appointment. My teacher gave me an extension on my homework, but lo and behold, they kept me at the hospital overnight! Now I have 3 hours until it's due and I've no idea where to even start.

Dan applies a force of 93 N on a heavy box by using a rope held at an angle of 57° with the horizontal. What are the vertical and horizontal components of the 93-N force?

I need to get the vertical and horizontal force for these problems, in Newtons. I don't know how, so an explanation would really be helpful. Thanks in advance to any help given!

$F_x = 93\cos(57^{\circ})$ N

$F_y = 93\sin(57^{\circ})$ N

go here and see how simple it really is ...
