If the sky diver releases her chute and an upward force of 800 Newtons is developed due to wind resistance, what will be the net force acting on her?

net force up = 800- m g

To calculate the net force acting on the skydiver, we need to consider the forces acting on her. There are two forces involved:

1. Weight (downward force): This force is due to gravity and is calculated using the formula Fg = m * g, where m represents the mass of the skydiver and g represents the acceleration due to gravity (approximately 9.8 m/s^2).

2. Wind resistance (upward force): The wind resistance force opposes the skydiver's motion and can be calculated using the formula Fw = -m * a, where m represents the mass of the skydiver and a represents the acceleration of the skydiver due to wind resistance.

Given that an upward force of 800 Newtons is developed due to wind resistance, we can conclude that Fw = 800 N.

Since these two forces are in opposite directions, the net force is the vector sum of these two forces. Therefore, to find the net force, we need to consider the direction of the forces.

If we assume that the downward force is positive, then the net force can be calculated as follows:

Net force = Weight - Wind resistance

Net force = m * g - (-m * a) [Note: The negative sign is due to the opposing direction of the force]

Net force = m * g + m * a

Net force = m * (g + a)

So, to find the net force acting on the skydiver, we need to know the values of mass (m), gravity (g), and acceleration due to wind resistance (a).
