An 80.0 kg person is parachuting and experiencing a downward acceleration of 2.50 m/s². The mass of the parachute is
5.00 kg. (a) What is the upward force on the open parachute from the air? (b) What is the downward force on the
parachute from the person?
Step 1
Create the free-body diagram for the parachute.
Use the checkboxes to select the correct vectors as instructed above. Move the vectors
to the correct starting points and orient them in the correct direction as instructed.
mg
FN
FA
Fp
Draw free-body diagram here
Key to Force Labels
mg = Gravitational force
f = Frictional force
FN = Normal force
FA = Air force
Fp = Person force
Point the acceleration vector
in the correct direction
45°
