Ajet plane comes in for a downward dive as shown in the figure below.
the bottom part of the path is a quarter circle having a radius of curvature of 350m . according to medical tests, pilots lose consciousness at an acceleration of 5.50g. at what speed (in m/s) will the pilot black out for this dive?

As we know that centripetal acceleration during circular motion is given by the formula

as we know that maximum value of acceleration is given as

here we know that

so here we will have

now we will have from above first equation

so maximum possible speed will be 137.4 m/s

moisture is lackin, and organic acids are scarce.
