Luz, who is skydiving, is traveling at terminal velocity when she changes position by going headfirst toward the ground

what happens to her motion?

she will continue to fall at the same terminal velocity because gravity has not changed.

she will slow down because the air resistance will increase and be greater than gravity.

she will speed up because air resistance will decrease and be less than gravity.

she will begin to fall in free fall because she will have no air resistance acting on her.

She will speed up because air resistance will decrease and be less than gravity.

Explanation:

As we know that when she is travelling at terminal speed then at that position the force due to gravity on her is counter balanced by the air drag or air friction.

Now as she change her position to head first then in that case the air drag will decrease due to aerodynamic shape

So here in that case net force in downward direction will be more and then will accelerate her downwards.

So we will say that as she will change her position then her speed will increase due to unbalanced force on her

so correct answer will be

She will speed up because air resistance will decrease and be less than gravity.
