The following equations give the \(x\) component of the position for four objects as functions of time:

(a) Which objects have a velocity that changes with time?

(b) Which object is at the origin at the earliest instant, and what is that instant?

(c) What is that object's velocity \(1 \mathrm{~s}\) after the instant you calculated in part \(b\) ?

object 1: x(t)=a, where a = 5 m object 2: x(t)=bt+c, where b = +4 m/s and c=-1 m object 3: x(t) = et + ft, where e = +5 m/s and f = -9 m/s object 4: x(t) =gt+h, where g = -3 m/s and b = +12 m.
