Chapter 2, Problem 73P

* The positions of objects A and B with respect to Earth depend on time as follows: $x{\left(t\right)}_{\text{A}}=10.0\text{m}-\left(4.0m/s\right)t;x{\left(t\right)}_{\text{B}}=-12\text{m}\text{+}\left(6m/s\right)t$. Represent their motions on a motion diagram and graphically (position- versus-time and velocity-versus-time graphs). Use the graphical representations to find where and when they will meet. Confirm the result with mathematics.
