The vector F is (12.0, -3.00) in rectangular notation. What is this same vector in polar notation? Express the angle as a positive number between 0° and 360°.

In rectangular notation, (12.0, -3.00) is in the 4th quadrant.
Magnitude = √[(12.0)² + (-3.0)²] = 3√17
Angle = tan⁻¹(-3.00/12.0) = 360° - 14° = 346°
Polar notation : (3√17, 346°)
Magnitude = √[(12.0)² + (-3.0)²] = 3√17
Angle = tan⁻¹(-3.00/12.0) = 360° - 14° = 346°
Polar notation : (3√17, 346°)
