a) to find the magnitude you take the square root of the sum of the squared components
b) show that the angle between those vectors is 90 ( θ = cos-1 ( A dot B ) / ( |A|*|B| ) )
c) work is equal to the integral of F dot ds
d) what do you think?

Thanks for the help, but I'm much much much more behind than that. For some reason the setup of this problem confuses me too much. I guess I'll leave it behind; I cant even understand how to find the components
