Okay, here are the steps to reconstruct the vector F from its components: 1) Use the Pythagorean theorem to find the magnitude F: F2 = Fx2 + Fy2 F2 = (−2)2 + (−4)2 F2 = 4 + 16 = 20 F = √20 = 4.5 N 2) Use the definition of tangent to find the angle θ: tanθ = Fy/Fx tanθ = −4.0/−2.0 θ = tan−1(2) = 63.4° So the vector F has a magnitude of 4.5 N and is directed at an angle of 63.4° counter-
