Free Fall vs Jetpack: Will He/She Stay Afloat?

AI Thread Summary
A person falling from the sky has a weak jetpack that can only generate an upward force equal to gravitational force (Fg). The discussion centers on whether the individual will stay afloat or crash, depending on how the thrust is aimed. The lack of specific acceleration details complicates the analysis of the situation. Participants note that the question requires more information to determine the outcome accurately. The thread has been closed due to a request for proper posting in the Homework Help forums.

There is a random person falling from the sky. He remembers that he has a jetpack. Unfortunately, his jetpack is weak and is only able to provide upward force equivalent to Fg.

WILL HE?SHE STAY AFLOAT OR WILL HE?SHE CRASH INTO THE GROUND?
What acceleration will he/she hit the ground?

Depends on which way he/she aims the thrust.
 
the thing is the question does not specify at all the acceleration its just an upwards force?
 
Thanks for your help

Thread 'Is 'Velocity of Transport' a Recognized Term in English Mechanics Literature?'

Here are two fragments from Banach's monograph in Mechanics I have never seen the term <<velocity of transport>> in English texts. Actually I have never seen this term being named somehow in English. This term has a name in Russian books. I looked through the original Banach's text in Polish and there is a Polish name for this term. It is a little bit surprising that the Polish name differs from the Russian one and also differs from this English translation. My question is: Is there...

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
