Can someone help me figure out the formula I need to use tosolve this problem?
Thanks! "Starship Enterprise is orbiting planet Qruqx IV (mass6.2·1024 kg, radius 6600 km) at an altitude of36000 km. What is its angular velocity?" I appreciate the help.... Can someone help me figure out the formula I need to use tosolve this problem?

Explanation / Answer

mass m = 6.2 * 10 ^ 24 kg radius R = 6600* 10 ^ 3 m altitude h = 36000* 10 ^ 3 m angular speed w = ? we know w = v / r                   = [ Gm / r ] / r                    =[ Gm / r ^ 3 ] where G = Gravitational constant = 6.67 * 10 ^ -11 N m ^2 / kg ^ 2             r = R + h = 42600 * 10 ^ 3 m plug the values we get w = 7.313 * 10 ^ -5 rad / s
