Question

a satellite of mass 1000kg is supposed to orbit the earth of a height of 2000km above the earth surface then speed in orbit

Answer 1

Hope this helps you

Answer 2

Here is your answer:

Explanation:

Speed of the satellite =  GM/ r+ h = gR2 / r = h

v=  9.8 x (6400 x 10^3) 2/ 10^6 x ( 6.4 + 2)

v = 9.8 x 6.4 x 6.4 x 10^6/ 8,4

v = 6.9 x 10^3 m/s = 6.9 Km/s
