Question

Two cats A and B moving along in a straight line. Car A is moving at a speed of 80KMph while car B is moving at a speed 50KMph in the same direction,find the magnitude and direction of a) the relative velocity of a car A with respect to B b) the relative velocity of a car B with respect to A

Answer 1

relative velocity of car A w.r.t B is 80-50=30KMph in direction of increasing velocity
relative velocity of car B w.r.t to car A is:
50-80=-30KMph in direction of decreasing velocity
