Kinematics Question 648

Question: A boat is moving with a velocity $ (3\hat{i}+4\hat{j}) $ with respect to ground. The water in the river is moving with a velocity $ (-3\hat{i}-4\hat{j})$ with respect to ground. The relative velocity of the boat with respect to water is

Options:

A) $ 8\hat{j} $

B)$ -6\hat{i}-8\hat{j} $

C) $ 6\hat{i}+8\hat{j} $

D)$ 5\sqrt{2} $

Show Answer

Answer:

Correct Answer: C

Solution:

[c] Relative velocity $ =(3\hat{i}+4\hat{j})-(-3\hat{i}-4\hat{j})=6\hat{i}+8\hat{j}. $
