Answer: [tex]1.5\ m/s^2[/tex]

Explanation:

Given

velocidad [tex]v=54\ km/h[/tex]

tiempo tomado [tex]t=10\ s[/tex]

Convertir km/h en m/s

[tex]\Rightarrow 54\ km/h\equiv 15\ m/s[/tex]

La aceleración está dada por la tasa de cambio de velocidad

[tex]\Rightarrow a=\dfrac{v}{t}\\\\\Rightarrow a=\dfrac{15}{10}\\\\\Rightarrow a=1.5\ m/s^2[/tex]

Por tanto, la aceleración es [tex]1.5\ m/s^2[/tex]
