Two particles `P` and `Q` start from rest and move for equal time on a straight line. Particle `P` has an acceleration of `X m//s^2` for the first half of the total time and `2 X m//s^2` for the second half. The particle `Q` has an acceleration of `2 X m//s^2` for the first half of the total time and `X m//s^2` for the second half. Which particle has covered longer distance ?

Two particles P and Q are moving on circle. At a certain instant of time both the particles and diametrically opposite and P has tangential acceleration 8 m//s^(2) and centripetal acceleration 5 m//s^(2) whereas Q has only e centripetal acceleration of 1 m//s^(2) . At that instant acceleration ("in" m//s^2) of P with respect to Q is
