A person driving through a field has velocity components that are 30 m/s west and 20 m/s south. What is the magnitude of the overall velocity?

Magnitude of the overall velocity = 36.06 m/s

Explanation:

30 m/s West in vector form = - (30î) m/s

20 m/s South in vector form = - (20j) m/s

The overall velocity = ( - 30î - 20j) m/s

Magnitude of the velocity (x, y) = √ (x² + y²)

Magnitude of the velocity = √ ((-30) ² + (-20) ²) = 36.06 m/s
