[SOLVED] I dont know if I did the problem right check please. 1. The problem statement, all variables and given/known data 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. 2. Relevant equations A=V^2/r 3. 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.
