A500-n parachutist opens his chute and experiences an air resistance force of 800 n. the net force on the parachutist is then

Force of 500 N is acting on the parachutist.

Parachutist applies 500 N force in downward direction.

300 N upward

Solution:

Parachutist feels air resistance of 800 N.

Thus, 800 N of force is acting in upward direction.

Total force acting on the parachutist is given by,

= air resistance force - force of parachutist

= 800-500

= 300 N

Direction of force is in upward direction because the air resistance force is more than force of parachutist.

d. air pressure decreases as altitude increases.

c) up is the direction the magnetic force is acting on the charge.
