Megan hits a softball into the stands. She rounds the bases and crosses home plate at 27km/h. Hey journey takes 6 seconds. What if Megan’s average acceleration

Respuesta :

calculista

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]
