Two particles P and Q start from rest and move for equal time on a straight line. Particle P has an acceleration of 2 m/s2 for the first half of the total time and 4 m/s2 for the second half. The particle Q has an acceleration of 4 m/ s2 for the first half of the total time and 2m/s2 for the second half. Which particle has travelled larger distance?
Assume that total time of journey = 2t
then distance travelled by P
Distance travelled by Q
