InterviewSolution

1.	A boat is moving with a velocity `3 hat i+ 4hat 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.A. `8j`B. `-6i-8j`C. `6i+8j`D. `5sqrt(2)`
Answer» Correct Answer - C `vec(v)_(b//g)=3i+4j` `vec(v)_(w//g)=-3i-4j` `vec(v)_(b//w)=vec(v)_(b//g)-vec(v)_(b//g)-vec(v)_(w//g)=6i+8j`
