particles A and B are moving along horizontal straight lines which lie in the west east direction. At a certain time, A passes a point P moving to the east with speed 5ms^-1 and constant acceleration 1ms^-2. Simultaneously, B passes a point Q east of P with speed 4ms^-1 towards the west but with constant acceleration 2ms^-2 towards the east. Given that the distance PQ is 28m, Calculate a) The distance of A from P when B reverse direction b) The time taken after the start for A to overtake c) The further time taken for B to overtake A
