{{}} If a river flows from west to east with constant velocity of 1.0 m s^-1 and a boat leaves south bank heading towards north with velocity of 2.40 m s^-1 , then resultant velocity of boat is A)2.6 m s^-1 B)2.7 m s^-1 C)2.8 m s^-1 D)2.9 m s^-1

Question

The resultant velocity of the boat can be found using the Pythagorean theorem since the velocities are perpendicular to each other: $\sqrt{(1.0)^2 + (2.4)^2} = \sqrt{1 + 5.76} = \sqrt{6.76} = 2.6 \, \text{m/s}$.
