A 60 kg jet pilot flies in a vertical loop of radius 2000 m. At the top of the loop she is moving with a speed of 340 m/s (Mach 1). What is the normal force exerted by the plane’s seat on her in Newtons?

Answer: buoyancy forceexplanation: in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

Wish i knew this to !

Hahahah jsu’s hsjshshsh. shjshshshsh.
