The human body can safely stand an acceleration of 9 times that due to gravity. With what minimum radius of curvature may a pilot safely turn the plane upward at the end of a dive if the plane's speed is 770kmph?

Question

anonymous · Answer

9g=v^2/r
g is acceleration due to gravity
v=velocity
r= radius of curvature

anonymous · Answer

formula comes by force balancing
ma=mv^2/r
m=mass
a=acceleration

anonymous · Answer

The confusion comes from what a human body feels! Is it the net force = mV^2/r or Normal force on you = mV^2/r

anonymous · Answer

its the normal force acting on u which makes the net force.

anonymous · Answer

yes, but do you feel the net force as 9mg or just the normal force as 10mg

anonymous · Answer

i think its 9mg only

anonymous · Answer

as our body cant safely withstand 10mg as per problem,

anonymous · Answer

and also the net effect is 9mg taking into account the mg force
