Explanation:
Average acceleration is defined as change in velocity divided by change in time.
Mathematically, a = [tex]\frac{\Delta v}{\Delta t}[/tex]
Since, it is given that change in velocity is 2 m/s. On the other hand, [tex]t_{1}[/tex] = 0 sec and [tex]t_{2}[/tex] = 4 sec.
Therefore, calculate average acceleration as follows.
a = [tex]\frac{\Delta v}{\Delta t}[/tex]
= [tex]\frac{\Delta v}{t_{2} - t_{1}}[/tex]
= [tex]\frac{2 m/s}{4 sec - 0 sec}[/tex]
= 0.5 [tex]m/s^{2}[/tex]
Therefore, we can conclude that average acceleration of the given particle is 0.5 [tex]m/s^{2}[/tex].
