Two cars A and B are at positions 50 m and100 m from the origin at t 0, They startsimultaneously with constant velocities 10 m/s and 5 m/s respectively in the same direction,Find the time at which they will overtake oneanother |

Answer» Let S be the distance from the point car A start to the distance where they both meet and t be the time taken to by both car to meetCar A:S=10tCar B:S-100 = 5t dividing both equation we get2S-200=SS=200 ie... they both meet at distance of 200m from the start point of A ... which implies the distance from origin is 200+100 = 300mtime taken =>S=10t=20 secondsthey take 20 seconds to meet |
