When the road is dry and coefficient of friction is new the maximum speed of a car in a circular path is 10 m per second if the road becomes a white and the coefficient of friction between new why and what is the medicines be written?
Answers
If friction is reduced then due to rain its half decreases (1/2). So when the friction is reduced = smoothness increases = the speed of the car increases (because the resistance of the road car tire decreases). And as a result, the speed drift faster than the first in the circular path -> speed will double
A coefficient of friction is a value that shows the relation between the two objects between the frictional force and the normal reaction between the included objects. It is a value that is sometimes used in physics to find an object's general power or frictional force when other methods are unavailable.
Coefficient of friction is shown. In that equation, there is frictional force, coefficient of friction, and general force.
Coefficient can be two different things. It is either coefficient of static friction, or coefficient of dynamic friction. Coefficient of stable friction is frictional strength between two objects when none of the objects is moving forward. Coefficient of dynamic friction is the force between two objects when an object moves, or if two things are moving forward against one another.
Coefficient of friction is dimension and there is no unit in it. This is a scalar, which means the direction of force does not affect the physical quantity.
Coefficient of friction depends on the objects that are producing friction. The value is generally ranging from 0 and 1 but can be larger than 1. The value of 0 means that there is no friction between the objects. It is only theoretically possible. There will be some friction when touching each other in the real world. The value of 1 means that the frictional force is equal to the normal force. Some people think that coefficient of friction can not be greater than 1, but this is not true. A coefficient of friction which is more than one, it means that friction is stronger than normal force. For example, in an object such as silicone rubber, a coefficient of friction can be more than one.
Friction force is the force imposed by a surface when an object moves on it - or attempts to cross it.
Friction force or friction force can be expressed
(1)
where
The frictional force (in Newton)
Static (μs) or dynamic (μk) friction coefficient (without dimension) and
Normal force (in Newton).
It can also be known as friction.
Maximum speed :
v = √μ rg
V2/V1 = √(μ2/μ1)
V2 = 10 ×√(μ/2/μ)
= 10/√2 m/s
