Given data
*The given speed of the car is u = 4.4 m/s
*The given acceleration of the car is
[tex]a=+0.63m/s^2[/tex]*The given time is t = 5.4 s
The formula for the final speed of the car is given as
[tex]v_f=u+at[/tex]Substitute the known values in the above expression as
[tex]\begin{gathered} v_f=(4.4)+(0.63)(5.4) \\ =7.80\text{ m/s} \end{gathered}[/tex]Hence, the final speed of the car is 7.80 m/s
