// Given data
h = 35800; // height of satellite orbit from earth in km
G = 6.67*10^-11; // Gravitational constant
M = 5.98*10^24; // mass of the earth in kg
Re = 6364; // radius of earth in km
i = 2; // inclination angle
// Calculations
u = G*M
r = Re+h
Vi = sqrt(u/r*10^3)*tan(i*%pi/180); // magnitude of velocity impulse
V = Vi/1000; // magnitude of velocity impulse in m/s
// Output
mprintf('Magnitude of velocity impulse = %d m/s',V);
