Sky Diver.. Acceleration?

Question

A sky diver of mass 80.0 kg (including parachute) jumps off a plane and begins her descent.
Throughout this problem use 9.80 m/s^2 for the magnitude of the acceleration due to gravity.

A) At the beginning of her fall, does the sky diver have an acceleration? A: No; the sky diver falls at constant speed. B: Yes and her acceleration is directed upward. Or C: Yes and her acceleration is directed downward.

B) At some point during her free fall, the sky diver reaches her terminal speed. What is the magnitude of the drag force F-drag due to air resistance that acts on the sky diver when she has reached terminal speed?
Express your answer in newtons.

Answer 1

When she leaves teh plane, she is accelerating downward due to gravity. Air resistance acts to decrease this acceleration.

When she reaches terminal velocity, the force of air resistance is equal to the force of gravity hence teh ari resistance exerts a force of 9.8 x 80 = 784 Nts upward.

Answer 2

the answer to A is C, the third one. acceleration down, due to gravity.

for B, when she reaches terminal velocity, the drag force is exactly the same maginitude as the force of gravity, G, in the opposite direction, straight up.
