What is the average velocity of the object between 14 and 22 seconds? A jet plane makes a downward dive as shown. The bottom part of the path is a quarter circle having a radius of curvature of 350 m. At what speed (in mph) will the pilot experience an acceleration of 5.5g? Use 1 mph = 0.447 m/s.

Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere. the winds blow from west to east in jet streams but the flow often shifts to the north and south. jet streams follow the boundaries between hot and cold air. the earth's rotation is responsible for the jet stream as well.
