Question

A woman falls to the ground while wearing a parachute. The air resistance on the parachute of the parachute is 500N. If the woman falls at a constant rate of 5m/s, then the gravitational force on her is
A) 500N
B) less than 500N
C) more than 500N
D) There is not enough information to draw a conclusion about the gravitation forces.

Answer 1

The gravitational force on the woman is A) 500 N

Explanation:

There are two forces acting on the woman during her fall:

• The force of gravity, $F_G$, acting downward
• The air resistance, $F_D$, acting upward

According to Newton's second law, the net force acting on the woman is equal to the product between the woman's mass and her acceleration:

$\sum F=ma$

where m is the mass of the woman and a her acceleration.

The net force can be written as

$\sum F = F_G - F_D$

Also, we know that the woman falls at a constant velocity (5 m/s), this means that her acceleration is zero:

$a=0$

Combining the equations together, we get:

$F_G-F_D = 0$

which means that the magnitude of the gravitational force is equal to the magnitude of the air resistance:

$F_G=F_D=500 N$

Answer 2

Answer: A) 500N

Explanation: To be in equilibrium the weight must be equal to 500N to balance out air resistance.
