Question

A boat is moving with a velocity 3i + 4j with respect to ground. The water in the river is moving with a velocity – 3i – 4j with respect to ground. The relative velocity of the boat with respect to water is

• A. 8j
• B. – 6i – 8j
• C. 6i +8j
• D. $5\sqrt{2}$

Answer 1

Answer: (C)

6i +8j

Answer 2

Relative velocity = (3i + 4j) – (– 3i – 4j) = 6i + 8j
