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.
Work out which of the displacement (S), initial velocity (U), acceleration (A) and time (T) you have to solve for final velocity (V). If you have U, A and T, use V = U + AT. If you have S, U and T, use V = 2(S/T) - U.
