Explanation:
Coefficients of Friction
Objects in physical contact produce friction which usually manifests as thermal energy being dissipated in the surface where the objects are interacting. It's usually harder to start to move an object from rest, that keeps moving it at a constant speed on the same surface. That is why there are two different coefficients of friction: the static and the dynamic. As mentioned, the static coefficient [tex]\mu_s[/tex] is greater than the dynamic coefficient [tex]\mu_d[/tex]. The car is already moving and is attempting to stop. The coefficient of friction is defined as
[tex]\displaystyle \mu_d=\frac{F_r}{N}[/tex]
Where Fr is the force of friction and N is the normal or the force the road pushes back up on the car. With the given data, we have
[tex]\displaystyle \mu_d=\frac{9,560\ N}{12,750\ N}[/tex]
[tex]\displaystyle \boxed{\mu_d=0.75}[/tex]
The coefficient of friction is dimensionless (doesn't have any units)
