Final answer:
The apparent weight of the pilot at the lowest point of the pullout is the sum of the pilot's true weight and the centripetal force, calculated using the mass of the pilot, velocity, and radius of the pullout maneuver.
Step-by-step explanation:
The apparent weight of the pilot at the lowest point of the pullout in an aerial maneuver can be determined by considering the forces acting on the pilot. Apparent weight is the normal force exerted on the pilot by the airplane seat while going through a circular motion at the bottom of the loop. This is a combination of the pilot's true weight (due to gravity) and the centrifugal force (due to circular motion).
To calculate this, we use the formula for centripetal force: Fc = mv2/r, where m is the mass of the pilot, v is the velocity at the lowest point, and r is the radius of the circular path. The pilot's apparent weight is the sum of his true weight (mg, where g is the acceleration due to gravity) and the centripetal force (Fc). Expressing the final answer includes considering the significant figures based on the precision of the given values.
