Each of four particles moves along an x axis. Their coordinates (in meters) as function of time (in seconds) are given by Particle `1:x(t) =3.5 -2.7t^(3)` Particle :2 `x(t)=3.5+2.7 t^(3)` particle 3: `x(t) =3.5+2.7 t^(2)` particle 4: `x(t)=3.5-3.4 t -2.7 t^(2)` Which of these particles have constant acceleration ?A.
