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

Click For Summary

Discussion Overview

The discussion revolves around a hypothetical scenario involving a person falling from the sky who has a weak jetpack that provides an upward force equivalent to gravitational force. Participants explore whether the individual will stay afloat or crash to the ground, as well as the implications for acceleration upon impact.

Discussion Character

  • Exploratory, Debate/contested, Homework-related

Main Points Raised

  • One participant questions whether the lack of specification regarding acceleration affects the scenario, noting that the upward force is not clearly defined.
  • Another participant suggests that the direction in which the thrust is aimed will influence the acceleration experienced by the individual.
  • A link to forum guidelines is provided, indicating that the discussion may not align with homework help protocols.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the implications of the upward force or the specifics of the acceleration, indicating multiple competing views remain.

Contextual Notes

The discussion lacks clarity on the definitions of forces involved and the assumptions regarding the jetpack's thrust direction and effectiveness.

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
