InterviewSolution

1.	In a reference frame a man A is moving with velocity `(3hati-4hatj)ms^(-1)` and another man B is moving with velocity `(hati+hatj)ms^(-1)` relative to A. Find the actual velocity of B.
Answer» `vecv_("actual")=vecv_(ref)+vecv_(ref)=[(hati+hatj)+(3hati-4hatj)]ms^(-1)=(4hati-3hatj)ms^(-1)`
