//Example 2.1.2
// Calculate the Orbital radius and Linear Velocity of Shuttle along its orbit
//Variable Declaration
re=6378.14 //radius of earth in km
h=250 //altitude in km
a=re+h
u=(3.986004418*10^5)
//Calculation
T=sqrt((4*(%pi^2)*(a^3)/u)) // Period of orbit in Sec
circum=2*%pi*a //circumference of orbut=2*pi*a in km
Vs=(2*%pi*a)/T //velocity in km/s
v=sqrt(u/a) //velocity by alternate method
//Result
disp(T,'Period of orbit in Sec')
disp(circum,'Circumference of Orbit in km')
disp(Vs,'Velocity of Satellite in Orbit in km/s')
disp(v,' Velocity of Satellite in Orbit in km/s(By Alternate Method)')
