Question

Can you calculate the orbital velocity of a satellite orbiting at an altitude of 500 km? Data: G = 6.673 x 10" SI units M = 5.972 x 10 kg: R 6371000 m; h = 500000 m​

Answer 1

THIS IS THE ANSWER

HOPE IT IS UNDERSTANDABLE

THANK

v =  √ 6.67 × 10 − 11 × 5.972 × 10 24 6371000 + 500000 6.67×10−11×5.972×10246371000+500000 ∴ v = 7613 ms-1 or 7.613 kms-1
