✔ 最佳答案
6360 m/s, 9840 km ?? a bit blurry.circumference of orbit is πd = 2πr = 2π(9,840,000 m) = 61,830,000 m
61,830,000 m / 6360 m/s = 9721 sec
1 circumference = 2π rad
1 circum / 9721 s x (2π rad/circum) = 0.0006463 rad/s
(45º/360º)61,830,000 m = 7,729,000 m

a
angular speed ω = V/r =6,360 m/sec / (9.84*10^6) m = 6.463*10^-4 rad/sec = 2PI/Tperiod T = 2PI/ ω = 6.2832*10^4/6.463 = 9,722 sec bdistance = 2PI*r/8 = 9840*3.1416/4 = 7,728 km
