And part A


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
