In order to calculate the acceleration, we can use the formula below:
[tex]a=\frac{v_f-v_i}{t}[/tex]If the final velocity is 16 m/s, the initial velocity is 4 m/s and the time is 4 seconds, we have:
[tex]\begin{gathered} a=\frac{16-4}{4}\\ \\ a=\frac{12}{4}\\ \\ a=3\text{ m/s^^b2} \end{gathered}[/tex]Therefore the acceleration is 3 m/s².
