Question

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

Answer 1

How fast is she going 

Answer 2

Answer:

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.
