Calculate the velocity of a satellite moving in a stable circular orbit about the Earth at a height of 2600 km.

• physics - forces -

Fgravity=Fcentripetal

GMearth/(radEarth+ 2600km)^2= mv^2/(radearth+2600)

solve for v.

change all distances to meters..

• physics - forces -

would m be the mass of the earth?

• physics - forces -

m is mass satellite.
And I forgot one on the left of that line.
Here is is corrected:

GMearth*m/(radEarth+ 2600km)^2= mv^2/(radearth+2600)

• physics - forces -

does that mean the mass of the statellite cancels? because the mass of the statellite isnt given

• physics - forces -

yes, the mass of the satellite divides out.
