On July 15, 2004, NASA launched the Aura spacecraft to study the earth's climate and atmosphere. This satellite was injected into an orbit 705 km above the earth's surface, and we shall assume a circular orbit.
a). How fast in km/s is the Aura spacecraft moving?
To maintain a circular motion, the centrifugal force (F) must be equal to
F = m*v^2/r where v is the ...
A few lines of calculations show how to calculate the speed of NASA's Aura spacecraft in orbit.
