Homework Statement
Can vectors with 180+(degrees) have a negative magnitude? I'm trying to find components of a vector that is going 260 km, 48 (degrees) south of east. So I'm confused whether the 260 is positive or not because of the -48 degrees.
Homework Equations
([itex]\vec{V}[/itex]) (sin[itex]\theta[/itex])
([itex]\vec{V}[/itex]) (cos[itex]\theta[/itex])
The Attempt at a Solution
(-260km)(sin(48)) or (260km)(sin(48)) =[itex]\vec{V}[/itex][itex]_{y}[/itex]
(-260km)(cos(48)) or (260km)(cos(48)) =[itex]\vec{V}[/itex][itex]_{x}[/itex]
Which one??
