Explanation:

Step1: Identify velocity-time points

From the graph: $v_1=3\ \text{m/s}$, $t_1=0\ \text{s}$; $v_2=15\ \text{m/s}$, $t_2=6\ \text{s}$

Step2: Apply acceleration formula

Acceleration is change in velocity over time.
$$a=\frac{v_2-v_1}{t_2-t_1}$$

Step3: Substitute values and calculate

$$a=\frac{15-3}{6-0}=\frac{12}{6}=2\ \text{m/s}^2$$
