    So, begin by writing down SUVAT for each particle.

    Particle p:
    S=?
    U=
    V=2.8
    A=0.12 ms
    T=0

    Particle Q
    S-?
    U-
    V-2.4 ms
    A-0.2ms
    T-3 seconds

    I think this is the suvat for both particles

    Yes, except your V values should be U values instead, as time is measured after they cross point A hence the initial velocity is their velocity at point A.

    So, you can work out their displacement equations
