## Homework Statement

"Determine the acceleration due to gravity on the planet Mercury which has a mass of 3.30*10^23kg and a diameter of 4878 km.

## Homework Equations

Gmp/rp2

Mp is mass of planet

Rp is radius of planet

## The Attempt at a Solution

First off I needed to change the diameter into the radius. In my class I have to convert km to m.

4878 km*1000= 4,878,000 m

4,878,000/2= 2,439,000

2,439,000 is the radius

Next, plugged in.

G=6.67*10^-11

Gmp/rp2

(6.67*10^-11)(3.30*10^23)/2,439,000^2 = 3.70 g on Mercury.

I'm pretty sure this is correct just want to make sure. Thanks for looking it over!
