When a fighter pilot makes a very quick turn, he experiences a centripetal acceleration. when this acceleration is greater than about 5.5 × g the pilot will usually lose consciousness ("black out"). consider a pilot flying at a speed of 890 m/s who wants to make a very sharp turn. what is the minimum radius of curvature that he can take without blacking out?

16.495 m

Explanation:

a = Centripetal acceleration = 5.5 g

r = Radius of turn

v = Velocity of fighter jet = 890 m/s

g = Acceleration due to gravity = 9.81 m/s²

The direction of the velocity vector keeps constantly changing in centripetal acceleration

The minimum radius of curvature that he can take without blacking out is 16.495 m

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
