Homework Statement
A geostationary satellite goes around the Earth in 24hr. Thus, it appears motionless in the sky and is a valuable component for telecommunications, including digital television. If such a satellite is in orbit around the Earth at an altitude of 35 800 km above the Earth's surface, what is the module of its centripetal acceleration?
Homework Equations
I believe I should use
ac = (4∏2r) / T2
Converted:
T= 24 hr = 86400s
r = 35800 km = 35 800 000 m = 3.58 x 107 m
The Attempt at a Solution
I plugged in the values:
ac = (4∏235 800 000) / 864002
ac = 0,189
The answer SHOULD be 0.223 m/s2
