Question

NASA wants to send several probes to orbit moons around Jupiter to find signs of life.

They specifically want to orbit the four Galileo moons Europa, Io, Ganymede, and

Calisto and record data from their surfaces. To orbit an object in space, the satellite must

be going the right speed known as orbit velocity. The orbit velocity equation can be

found below. Its inputs are the mass gravitational constant , and the radius of orbit from

the centroid of the object. Use the following equation and create a function called v_orbit

that inputs and r. Use the following information to create and test your function.

*Use Matlab

rorbit = 10,000 km and 5,000 km

Europa=3201 km^3/s^2

Vorbit =/r

ANSWER:

function vel = v_orbit (u, r)
vel = sqrt ((u/r));
end

a = v_orbit (4,1);
disp (4);
disp (a);
