The slope's stability to vehicles traveling on it is high, thus the builder can employ materials that strengthen or preserve the slope's provided stability so that cars do not slide on the slope.
<h3 /><h3>What is the friction force?</h3>
It is a type of opposition force acting on the surface of the body that tries to oppose the motion of the body. its unit is Newton (N). Mathematically it is defined as the product of the coefficient of friction and normal reaction.
On resolving the given force and acceleration in the different components and balancing the equation gets.Components in the x-direction.
The given data in the problem is
the ratio of resisting forces to driving forces is 0.73
f is the resisting force
F is the driving force

The slope's stability to vehicles traveling on it is high.
Hence the builder can employ materials that strengthen or preserve the slope's provided stability so that cars do not slide on the slope.
