Here is the answer for the question - During an experiment, a crate is pulled along a rough horizontal surface by a force F⃗ and the magnitude of the acceleration along the x direction, ax, is measured.(Figure 1) The vector F⃗ has a component along the x direction of magnitude Fx. The experiment is repeated several times, with different values of Fx each time, while maintaining a constant value for, Fy, the vertical component of F⃗ .. You'll find the correct answer below

During an experiment, a crate is pulled along a rough horizontal surface by a force F⃗ and the magnitude of the acceleration along the x direction, ax, is measured.(Figure 1) The vector F⃗ has a component along the x direction of magnitude Fx. The experiment is repeated several times, with different values of Fx each time, while maintaining a constant value for, Fy, the vertical component of F⃗ . Part B Create a plot of the force of kinetic friction, fk, versus the x component of the pulling force, Fx, for the experiment. Let the point Fmin, along the horizontal axis, represent the minimum force required to accelerate the crate. Choose the graph that most accurately depicts the relationship among fk, Fx, and Fmin. (Figure 3)

The Correct Answer is

D (graph blank halfway and then vertical dotted line and then horizontal red line)(The most important things to keep in mind when dealing with kinetic friction are the following:Only an object that is sliding with respect to a surface can be acted upon by the force of kinetic friction.fk points in a direction that is parallel to the surface of contact and opposes the motion of the object.fk=μkn, where μk is the coefficient of kinetic friction and N is the magnitude of the normal force.)
