(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A satellite is in a circular orbit about the earth (M = 5.98 x 1024 kg). The period of the satellite is 9.93 x 104 s. What is the speed at which the satellite travels?

2. Relevant equations

v=(2*pi*r)/T

v=sqrt((GMe)/r)

3. The attempt at a solution

sqrt[((6.67x10^-11)*(5.98x10^24))/r) = 2*pi*r / T

T = 2piR^3/2 / (sqrt[GMe])

r = 8.414 x 10^15

v = 2*pi*r / t

v = 5.324 x 10^11 m/s
