A jet plane comes in for a downward dive. The bottom part of the path is a quarter circle having a radius of curvature of 350 m. According to medical tests, pilots lose consciousness at an acceleration of 5.50 g. At what speed (in m/s and mph) will the pilot black out for this dive?
I know that v=sqrt(a*r), which will be in m/s for the first question and then I have convert m/s into mph for the second question which is easy as pie. The only thing is I don't know what the g in the 5.50g acceleration means...can someone help me please? Thanks a bunch.

g is the acceleration due to earth's gravity so, as you suspected, 9.8 m/s^2

'g' here is acceleration due to gravity of earth, which is equal to 9.80665 metre/second^2

Yes.
g = 9.8 m/s^2

5.5g = 5.5(9.8 m/s^2) = 53.9 m/s^2
