Question

Each of four particles moves along an x axis. Their coordinates (in meters) as functions of time (in seconds) are given by
particle 1: x(t) = 3.5 - 2.7t3
particle 2: x(t) = 3.5 + 2.7t3
particle 3: x(t) = 3.5 + 2.7t2
particle 4: x(t) = 3.5 - 3.4t - 2.7t2
Which of these particles have constant acceleration?
A) All four
B) Only 1 and 2
C) Only 2 and 3
D) Only 3 and 4
E) None of them
