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}. $
