	/// Example06: Let's Go Loop-The-Loop
	/// A pilot of mass m in a jet aircraft executes a loop-the-loop, 
	/// as shown in Figure 6.7a. In this maneuver, the aircraft moves
	/// in a vertical circle of radius 2.70 km at a constant speed 
	/// of 225 m/s. Determine the force exerted by the seat on 
	/// the pilot. (A) at the bottom of the loop and (B) at the 
	/// top of the loop. Express your answers in terms of the 
	/// weight of the pilot mg.
	/// n_bottom = 2.91 mg
	/// n_top = 0.913 mg
