You can use them by analyzing the way you can solve it.
To solve this problem it is necessary to apply the concepts related to the conservation of energy, through the balance between the work done and its respective transformation from the gravitational potential energy.
Mathematically the conservation of these two energies can be given through

Where,
W = Work
Final gravitational Potential energy
Initial gravitational Potential energy
When the spacecraft of mass m is on the surface of the earth then the energy possessed by it

Where
M = mass of earth
m = Mass of spacecraft
R = Radius of earth
Let the spacecraft is now in an orbit whose attitude is
then the energy possessed by the spacecraft is

Work needed to put it in orbit is the difference between the above two


Therefore the work required to launch a spacecraft from the surface of the Eart andplace it ina circularlow earth orbit is

"Though a force, or a resulting sum of forces, may be centripetal, there is not an actual "Centripetal Force" that would appear on an FBD. Since an FBD is a diagram of physical forces at work upon a body, and a centripetal force is not the reaction of some physical object upon another, it would not be proper to show it. You might have a tension force, a weight force, a normal force, electric forces, magnetic forces, or any number of reactions, but actually labeling any of them "centripetal" would be unconventional".
