// Given data
h = 150; // height of satellite from earth in km
G = 6.67*10^-11; // Gravitational constant
M = 5.98*10^24; // mass of the earth in kg
Re = 6370; // radius of earth in km
// Calculations
u = G*M
V = sqrt(u/((Re + h)*10^3)) // orbital velocity
V1 = V/1000; // orbital velocity in km/s
// Output
mprintf('Orbital velocity = %3.3f km/s',V1);
