A pilot performs an evasive maneuver by diving vertically at 310 .If he can withstand an acceleration of 9.0 's without blacking out, at what altitude must he begin to pull out of the dive to avoid crashing into the sea?
I think the only equation we should use is
so it is not hard, but the question is , what's the total accelration of it, is it 9*g or is it 8*g, i am saying ,no matter what i tried, just don't match with the answer.
Why would you pick that equation? I would think this is a centripetal acceleration problem. It says the pilot pulls out of the dive, it doesn't say he stops in midair! If he starts to trace out a circle as he pulls up (at the speed and acceleration given), what is the maximum radius that circle can be so he doesn't run into the water?
