A boat moves northward at a speed of \(5.0\) m s\(^{-1}\) relative to the water. The river flows eastward at \(3.0\) m s\(^{-1}\).\n\n(i) Find the speed and direction of the boat relative to the ground.\n(ii) Determine the component of the boat's ground‑velocity along the northeast direction (i.e., at \(45^{\circ}\) to the north).

Answer Options

A. 6.40 m s⁻¹ at 45° east of north; component along NE = 6.40 m s⁻¹
B. 4.90 m s⁻¹ at 31° east of north; component along NE = 4.90 m s⁻¹
Correct Answer C. 5.83 m s⁻¹ at 31° east of north; component along NE = 5.66 m s⁻¹
D. 5.83 m s⁻¹ at 20° east of north; component along NE = 5.20 m s⁻¹
Correct Answer
C
Correct Option:
5.83 m s⁻¹ at 31° east of north; component along NE = 5.66 m s⁻¹
