A pilot with a mass of 50 kg comes out of a vertical dive in a circular arc such that at the bottom of the arc her upward acceleration is 3.5g. (a) How does the magnitude of the force exerted by the airplane seat on the pilot at the bottom of the arc compare to her weight? (b) Use Newton’s laws of motion to explain why the pilot might be subject to a blackout. This means that an above normal volume of blood “pools” in her lower limbs. How would an inertial reference frame observer describe the cause of the blood pooling?
