Homework Statement

If I can get help with problem A) I should be able to figure out the rest on my own.

Homework Equations


None that I know of?


The Attempt at a Solution




When I see the word component of the net force, I tend to get a bit confused, but if you have something like

<1,2> <3,4> <5,6>

it would be <9,12>

so my gut instinct is to go ahead and just ad up the forces, to get 14

there arent answers in the back of my book for certain questions so I have no idea if its right though I doubt it

thanks

If you follow the path of F1, your position will be further up AND further left.
For F2, the position will be further up AND further right
For F3, the position will be only further down, no movement relative to left or right.

Relative movements that move to the left or right, up or down are the components.

You find the net movement.
