Given:
The initial velocity of the object is
[tex]v_i\text{ = 53 m/s}[/tex]The final velocity of the object is
[tex]v_f=\text{ 77 m/s}[/tex]The time taken by the object is t = 78 s
To find the object's acceleration.
Explanation:
The object's acceleration can be calculated as
[tex]\begin{gathered} a=\frac{v_f-v_i}{t} \\ =\frac{77-53}{78} \\ =0.308\text{ m/s}^2 \end{gathered}[/tex]The acceleration of the object is 0.308 m/s^2
