What’s the minimum coefficient of friction needed if the car is to stay on the road ?, The **minimum friction coefficient** required is 0.4.

Furthermore, What is the ideal speed to take a 126.0 m radius curve banked at 20.0 angle ?, Question: 1. **What Is The Ideal Speed To Take** A 75 **M Radius Curve Banked At A 20.0**° **Angle**? ____ m / s 2.

Finally, How do you find the coefficient of friction with radius and velocity ?, That is, we must have a **coefficient** of static **friction** of _{s} = v^{2}/ gr to provide the **friction** force to allow a car, traveling at **speed** v, to make it around a flat curve of **radius** r. This is the maximum **speed** that a curve of **radius** r can be taken when the **coefficient** of static **friction** between tires and pavement is _{s}.

## Frequently Asked Question:

### What is the maximum speed at which the car can turn without slipping?

The maximum velocity for the car is about 12 **m / s**.

### What is the maximum speed at which a car can round a curve?

Find the **maximum speed at which a car can** turn **round a curve** of 30m radius on a level road if coefficient of friction between the tires and road is 0.4. Takeg = 10m / s2. υ = √μrg = √0.4 × 30 × 10 = √120 = 11m / s.

### When a vehicle is taking a turn on an unbanked road without slipping in or skidding out the necessary centripetal force is provided by the?

In case of earth, gravitational **force** provides the **necessary centripetal force** and in case of **vehicle** in a curved **path**friction **force** provides that **necessary centripetal force**.

### How do you find the coefficient of friction with velocity?

The **formula to calculate** the **coefficient** of **friction** is μ = f ÷ N. The **friction** force, f, always acts in the opposite direction of the intended or actual motion, but only parallel to the surface.

### How do you solve for coefficient of friction?

The **coefficient of friction** (fr) is a number that is the ratio of the resistive force of **friction** (Fr) divided by the normal or perpendicular force (N) pushing the objects together. It is represented by the **equation**: fr = Fr / N.

### How do you find the coefficient of friction in circular motion?

That is, we must have a **coefficient** of static **friction** of _{s} = v^{2}/ gr to provide the **friction** force to allow a car, traveling at speed v, to make it around a flat curve of radius r. This is the maximum speed that a curve of radius r can be taken when the **coefficient** of static **friction** between tires and pavement is _{s}.

### What is the coefficient of friction between the car’s tires and the road?

Jones and Childers report **coefficients of friction** of about 0.7 for dry **roads** and 0.4 for wet **roads**.

### What is the minimum coefficient μs of static friction between the road and the car?

The **minimum coefficient** μ_{s} of **static friction between the road and the car** is 0.612.

### What minimum coefficient of friction is needed?

The **minimum coefficient** of static **friction** can be obtained from this equation: If the velocity of the car is 72 km / hr (20 m / s) and the radius of curvature R = 190 m, the **minimum** value of the **coefficient** of static **friction** is 0.21.

### How does friction keep a car on the road?

When a **car** slows down, the **friction** between the **road** and the tires helps to bring the **car** to a stop as the wheels slow down. It is the **friction** between the wheels and the brake pads that causes the wheels to slow down. … Even if the wheels stopped turning, the **car would keep** sliding over the low-**friction roads**!!

### What is friction on a car?

**Friction** is a resisting force that resists the relative motion of two surfaces. Simply put, when driving, the engine generates a force on the driving wheels that moves the **vehicle** onwards. **Friction** is the force that opposes the tire rubber from sliding on the road surface.

### Why does driving on a road require friction?

Explain why **driving on a road requires friction**. … **Friction** between the tires and the **road** enables the tires to push against the **road** and vice versa so that the car experiences a net force and moves forward or makes a turn. To increase frictionon an icy **road**you could put salt or sand on the **road**.

### How does friction affect the speed of a car?

Simply so, how **does friction affect** a **car’s speed**? **Friction** may slow the **car** down as it moves along the road, but it is also the force that enables the **car** to move forward at all. So, it is the force of **friction** that makes a **car** accelerate forward and also decelerate to a stop.

### What type of friction stops a car?

Anti-lock brakes prevents the wheels from locking and sliding and provide the operations of wheels turning while stopping – this way, the more efficient **friction** (static **friction**) is used to **stop** the **vehicle**; the **vehicle** will **stop** in shorter time and distance and you will have a better control of your **vehicle**.

### What should be the minimum coefficient of friction?

The **minimum coefficient** of static **friction** can be obtained from this equation: If the velocity of the car is 72 km / hr (20 m / s) and the radius of curvature R = 190 m, the **minimum** value of the **coefficient** of static **friction** is 0.21.

### What minimum coefficient of static friction is required?

If the velocity of the car is 72 km / hr (20 m / s) and the radius of curvature R = 190 m, the **minimum** value of the **coefficient of static friction** is 0.21.

### Is the coefficient of friction less than 1?

The **coefficient of friction** depends on the objects that are causing **friction**. The value is usually between 0 and **1** but can be greater **than 1**. A value of 0 means there is no **friction** at all between the objects; such is possible with Superfluidity. … A value of **1** means the **frictional** force is equal to the normal force.
