Velocity and acceleration both remain positive. Velocity and acceleration both become negative. Velocity remains positive but acceleration becomes negative. Velocity becomes negative but acceleration remains positive.
When a person parachutes from a plane, she travels at about 67 meters per second. When she pulls her cord and her chute opens, she slows to about 3 meters per second. If the velocity and acceleration are both considered positive before the chute opens, how do her velocity and acceleration change when the chute opens?

Options:
- Velocity and acceleration both remain positive.
- Velocity and acceleration both become negative.
- Velocity remains positive but acceleration becomes negative.
- Velocity becomes negative but acceleration remains positive.

Velocity remains positive but acceleration becomes negative.
