Question 118

A boat travels across a river. It has a velocity component of magnitude v1 v_1\,v1​ perpendicular to the riverbank and another velocity component of magnitude v2 v_2\,v2​ parallel to the riverbank.

Which of the following expressions represents the magnitude of the boat's resultant velocity, vvv?

A

v12+v22\sqrt{v_1^2 + v_2^2}v12​+v22​​

B

v1+v2v_1 + v_2v1​+v2​

C

v1+v2\sqrt{v_1 + v_2}v1​+v2​​

D

v12+v22\sqrt{v_1^2} + \sqrt{v_2^2}v12​​+v22​​
