Apilot can withstand an acceleration of up to 9g, which is about 88 m/s2, before blacking out. (a) what is the acceleration experienced by a pilot flying in a circle of constant radius at a constant speed of 515 m/s if the radius of the circle is 3320 m? (b) does the pilot make the turn without blacking out?

Centripetal acceleration = (speed)² / (radius)

Centripetal acceleration of our intrepid pilot = (515 m/s)² / (3,320 m)

Acceleration = (265,225 m²/s²) / (3,320 m)

Acceleration = (265,225 / 3,320) m/s²

a).  Acceleration = 79.9 m/s²

b).  79.9 m/s² is less than 88 m/s² .  So if our pilot has been taking care of himself, and has kept up with his required physical training, then he will make the turn without blacking out.

this is poiselle's equation from fluid mechanic in physics. mech eng
