Problem

An artificial satellite of negligible size is launched into a circular orbit

400\,\text{km}

above the Earth’s surface. a. (a) Calculate the orbital speed of the satellite. b. (b) Determine the time period of revolution in minutes. c. Given:

G = 6.67\times10^{-11}\,\text{N m}^2\text{kg}^{-2}

M_{E} = 6.0\times10^{24}\,\text{kg}

R_{E} = 6.4\times10^{6}\,\text{m}

. Assume the orbit is circular.
