Question

A parachutist is falling at terminal velocity, without her parachute open, What is the direction of her motion, and what is the direction of her acceleration, immediately after she opens the parachute?​

Answer 1

Direction - Downwards

Acceleration - Upwards

Step-by-step explanation:

Terminal velocity means the net force was 0, so when the parachute is introduced the parachutist will feel an unbalanced force upwards thus being accelerated upwards. Still the motion is still going down as although there is an Acceleration upwards, it will take some time for it to accelerate enough to make the velocity 0
