Given the velocities, a drone's ground velocity is the vector sum v⃗ground=v⃗drone+v⃗wind\vec v_{ground}=\vec v_{drone}+\vec v_{wind}. The drone's velocity relative to the air is v⃗drone=⟨4,3⟩\vec v_{drone}=\langle 4,3\rangle m/s (4 m/s east, 3 m/s north). The wind is v⃗wind=⟨−1,0⟩\vec v_{wind}=\langle -1,0\rangle m/s (1 m/s west). What is the magnitude of the resultant ground velocity ∣v⃗ground∣|\vec v_{ground}|?
