Question

a boat is moving with a velocity 3i+4j w. r. t the ground. the water in the river is moving with a velocity 3i-4j. the relative velocity of boat w. r. t​

Answer 1

Answer:

relative velocity is( 3i+4j) - (3i-4j)

=3i -3i +4j +4j

=8j

Answer 2

8jˆ

−6iˆ−8jˆ

6iˆ+8jˆ

52–√)

Answer :

C

Solution :

( c) Relative velocity of boat with respect to water is  

v→b−v→w=3iˆ+4jˆ−(−3iˆ−4jˆ)=6iˆ+8jˆ.
