Two particles A and B start from rest and move for equal time on a str

1.	Two particles A and B start from rest and move for equal time on a straight line.The particle A has an acceleration a for the first half of the total time and 2a for the second half. The particle B has an acceleration 2a for the first half and a for the second half. Which particle has covered larger distance?answer plzz!!
Answer» using SECOND equation of MOTION to find the distance TRAVEL in total time, and use first equation of motion to determine the velocity of object at a point where its ACCELERATION changes
