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

[Dhruvish]

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?

What acceleration will he/she hit the ground?

Depends on which way he/she aims the thrust.

 

[Dhruvish]

the thing is the question does not specify at all the acceleration its just an upwards force?
