Chapter 2, Problem 33E

To determine

The acceleration for each graph segment ${\overline{a}}_{\left(0-4.0\right)\text{s}}$ is $\underset{\_}{2.0\text{m}/{\text{s}}^2}$, ${\overline{a}}_{\left(4.0-10.0\right)\text{s}}$ is $\underset{\_}{0}$ and ${\overline{a}}_{\left(10.0-18.0\right)\text{s}}$ is $\underset{\_}{-1.0\text{m}/{\text{s}}^2}$.
