find the centripetal acceleration during a turn of a race car. please help!?

it's not fair to have people answer your homework questions on here....

but.. i will tell you that the question itself is bullshit..

the reason why is because G forces in race cars travel horizontally... you cannot black out from horizontal g forces...

You black out in a fighter plane because when you pull back on the stick, your body gets heavier and the blood rushes from your head to your feet and you go black.. if you push the stick down, the blood rushes to your head and you "red out"...


so taking a corner in a car would not effect you in that way unless you were laying sideways in the car when you took the turn, which doesn't happen.............


So give that to your professor...................

p.s. i dont think there's a car in the world that can handle a solid 8g turn on a flat circular track..


it IS possible however that they could black out if the track was at an extreme slope and they were essentially driving ON a 90 degree wall at some insanely fast speed to keep them there...

but that would be in the 400-600 mph range to make them stay on the wall and generate 5 g-s

i dunno....................
 
At a practice for a recent automobile race, officials found that the drivers were nearly "blacking out" which led to cancellation of the race. THe cars were traveling at about 240 mi/h, and the track was approximately 1.5 mi long. find the centripetal acceleration during a turn and compare it with the physiological limit of approximately 8 x g. Assume the track is circular.

please show work. thanks so much!
