Question
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

Second particle

Area under (v, t) graph gives displacement. For graph (2) area is more.
