Question

Problem 5.46 Part A Calculate the speed of a satelite moving in a stable circular orbit about the Earth at a height of 4810 km Express your answer using three significant figures and include the appropriate units. HAO? Value Units

Answer 1

here,

the height of satellite , h = 4810 km

h = 4.81 * 10^6 m

the radius of Earth , r = 6.37 * 10^6 m

the speed of satellite , v = sqrt( G * M /(r + h))

v = sqrt( 6.67 * 10^-11 * 5.98 * 10^24 /(6.37 * 10^6 + 4.81 * 10^6))

v = 5973 m/s

the speed of satellite is 5973 m/s
