You are given a vector in the xy plane that has a magnitude of 83.0 units and a y component of -68.0 units.
What are the two possibilities for its x component? X1,X2 = 47.6, -47.6
Assuming the x component is known to be positive, specify the magnitude of the vector which, if you add it to the original one, would give a resultant vector that is 80.0 units long and points entirely in the -x direction. (V=?)
Specify the direction of the vector. (degrees above the -x-axis)
