Answer:
[tex]a=1.25\frac{m}{sec^2}[/tex]
Explanation:
we know that
The formula to calculate the acceleration is
[tex]a=\frac{V_2-V_1}{t}[/tex]
we have
[tex]V_1=0\\V_2=27\ km/h[/tex]
[tex]t=6\ sec[/tex]
Remember that
[tex]1\ km=1,000\ m\\1\ h=3,600\ sec[/tex]
Convert km/h to m/sec
[tex]27\ km/h=27(1,000/3,600)=7.5\ m/sec[/tex]
Find the acceleration
[tex]a=\frac{7.5-0}{6}[/tex]
[tex]a=1.25\frac{m}{sec^2}[/tex]
