From EK physics book 1st 30 minute test.
My question is in regards to the passage about a guy being shot from a cannon. In the passage it says:
"the force on him while inside the cannon was so great that he would momentarily lose consciousness during the stunt"
he is shot at 53 degrees from horizontal, initial velocity 27 m/s.
So the first question/solution I am confused by is:
" From the information in the passage, which of the following factors most likely plays the greatest role in Zachini's loss of conciousness?
-->velocity, height, acceleration, or momentum
ANS: The passage says that it is the "propulsion" that causes the loss of conciousness. In other words, the force on Zacchini causes him to accelerate at a rate so great that he loses conciousness.
I think that something to do with inertia, or impulse would be a better answer assuming that his loss of conciousness is due to the blood temporarily flowing out of his head, or rather staying in place while his body begins accelerating. Is this line of thinking wrong?
Which would be the best answer if the possible answers were: inertia, momentum, impulse, or acceleration?
Any other thoughts, clarifications are much appreciated. I still am slightly confused by whether 'centrifugal' force in this case be attributed to inertia of the blood or the relation of an impulse being a temporary force over short time and whether to attribute the effects to the rapid change in acceleration in opposite direction, which in its equation form is equal to a change in momentum no?
