Answer:
The force F is created by the reaction of the Earth to the thrust of the rods, whereby the thrust is created by a force of action and reaction.
Explanation:
To answer this question, let's write Newton's second law of the two axes
Y Axis
Fy + N - W = 0
Fy + N = W
X axis
Fx - fr = 0
Fx = fr
The force F is created by the reaction of the Earth to the thrust of the rods, whereby the thrust is created by a force of action and reaction.
The direction of this force is along the length of the rods that are in an Angle, where the x and y components of the force come from
In general this force is small because the rubbing of the skis is small
The the horizontal force pushing him forward, is created by the reaction of the Earth to the thrust of the rods.
The two axes in the Newton's second law of motion,
For, Y Axis
Fy + N - W = 0
Fy + N = W
For, X axis
Fx - Fr = 0
Fx = Fr
Where,
Fx- force in the horizontal or x- axis.
The the horizontal force pushing him forward, is created by the reaction of the Earth to the thrust of the rods.
