Fallin with constant speed what is the force of air resistnace

Homework Statement

A 1.26 samara-the winged fruit of a maple tree-falls toward the ground with a constant speed of 1.1
What is the force of air resistance exerted on the samara?

Homework Equations

F=ma I thought that the force of air resistance would have to be equal to mg

The Attempt at a Solution

I tried 12.4N but said I was wrong, not sure what to do now? Any help please.

Hey man the fruit experience a drag force and a resistive force(air resist) against its motion so the forces in the x direction of the fruit would be f+Fa=ma where f is the drag force and Fa the air resist. constant speed would mean the terminal velocity with that you can find the drag force just use these values and you can find the air resistance.

The force of air resistance, also known as drag, is a complex force that depends on many factors such as the shape and size of the object, the density of the air, and the speed at which the object is moving. It cannot be simply calculated using the formula F=ma. In this case, the samara is a small, lightweight object with a large surface area, so it will experience a significant amount of air resistance. However, without more information about the specific conditions and characteristics of the samara, it is not possible to accurately calculate the force of air resistance. Additionally, the constant speed of 1.1 m/s does not provide enough information to determine the force of air resistance. It is important to note that the force of air resistance will be equal and opposite to the force of gravity (mg) at terminal velocity, when the object is falling at a constant speed with no acceleration. In summary, without more information, it is not possible to accurately determine the force of air resistance on the samara.
