Homework Help: Downward force of the plane problem

  1. Mar 14, 2009 #1
    1. The problem statement, all variables and given/known data
    why does a pilot tend to black out when pulling out of a steep dive?

    2. Relevant equations
    Newton's 2nd and 3rd laws

    3. The attempt at a solution
    I think the pilot passes out because the downward force of the plane pushes all the blood away from his brain and causes him to pass out.

    I read the rules of this forum so I don't expect an answer. But please push me in the right direction because I know I am forgetting something.

    Re: Forces

    Almost. But I don't think the plane is pushing down. What forces are associated with circular motion, because it's the pulling out of a dive, you know a radius and a high speed, as the pilots say "pulling G's". How is that force directed may be more to your interest?

    Hi aaronb! :smile:

    I think it's more Newton's first law …

    if you bounce off a trampoline, what does your blood "want" to do? :wink:
