What is the centripetal acceleration of the earth as it travels around the sun when Earth has an orbital radius of 1.5 x 10^11 m and an average orbital speed of 29.7 km/s

Respuesta :

Answer: [tex]0.0058 m/s^{2}[/tex]

Explanation:

Centripetal acceleration [tex]a_{C}[/tex] is calculated by the following equation:

[tex]a_{C}=\frac{V^{2}}{r}[/tex]

Where:

[tex]V=29.7 \frac{km}{h} \frac{1000 m}{1 km}=29700 m/s[/tex] is the Earth's orbital speed

[tex]r=1.5(10)^{11} m[/tex] is the orbital radius

[tex]a_{C}=\frac{(29700 m/s)^{2}}{1.5(10)^{11} m}[/tex]

[tex]a_{C}=0.0058 m/s^{2}[/tex]
