A model rock is shot into the air. Once it starts to fall a parachute is deployed. Draw a free body diagram of the rocket with the parachute deployed

ok well there is gravity
does the parachute exert a force upward? onto what? what do i call this force?
Answered by Dr Russ
Force down is mg where m is the mass and g is the acceleration due to gravity

Force up is Air resistance
Answered by drwls
A free body diagram of the rocket with parachute attached will have an air resistance force upwards (when falling) and a weight force (m g) downwards. There will be a lesser air resistance force on the rocket than on the psrachute.
