**[SOLVED] I don't know if I did the problem right check please.**

## Homework Statement

A jet is diving vertically downward at 1200km/hr

the pilot can withstand a maximum acceleration of 4G, before losing consciousness, at what height must the plane start a quarter turn to pull out of the dive? Assume the speed constant.

## Homework Equations

A=V^2/r

## The Attempt at a Solution

for this circular motion we know that h = radius of the circle

so

4G=(1200km/hr)^2/h

4G=4*9.8m/s=39.2m/s=508032km/hr^2(Not sure if convert it right)

508032=1200^2/h

h=2.834Km

Is this right, the answer has to be in Km so I convert the 4G.
