Are the forces on the parachutes balanced? A. The parachutes fall at a constant speed, so the forces are balanced.
B. There is a change in motion, so the forces are balanced.
C. The parachutes fall at a constant speed, so the forces are unbalanced.
D. There is a change in motion, so the forces are unbalanced.

When the parachute opens, air resistance becomes much greater than gravity. The forces are no longer balanced and this changes her speed.

Explanation:

Eventually the upward force of the air equals the downward force of gravity. When forces are balanced the speed remains constant.
