Answer» h the cars A and B meet at C which is at kilometres away from initial position of car B, after time seconds. The car B moves with speed of WITHOUT acceleration.By SECOND equation of motion, DISPLACEMENT of car B will be,The car A moves with speed of but has an acceleration of By second equation of motion, displacement of car A will be,Subtracting (1) from (2),Then (1) becomes,Hence 5 km is the ANSWER. |
