The velocity of a car A is to 5î. The velocity of another car B is 22î – 7&jcirc;. What is the relative velocity of A with respect to B?

(a) -17î + 7&jcirc;

(b) 7î + 17&jcirc;

(c) -7î + 17&jcirc;

(d) -17î + 7&jcirc;

I have been asked this question by my college director while I was bunking the class.

The question is from Motion in a Plane topic in chapter Motion in a Plane of Physics – Class 11

Right choice is (a) -17î + 7&jcirc;

To explain I would say: The formula for calculating relative velocity of a body with respect to another body is- relative velocity = Velocity vector of A – Velocity vector of B. Hence, here, the relative velocity = velocity of B – velocity of A = -17î + 7&jcirc;.
