Friction provides the force needed for a car to travel around a flat circular race track.

. Friction is a resisting force that resists the relative motion of two surfaces. A minimum coefficient of friction is needed or the car will move in a. Though friction can provide necessary centripetal force the banking of roads is considered as advantageous in highways.

Friction provides the force needed for a car to travel around a flat circular race track. Friction provides the force needed for a car to travel around a flat circular race track. Solution Let v is the maximum speed of the car at which it can safely travel.

The coefficient of friction To find The maximum speed of car. The centre of gravity of a car is 0. The centripetal force acting on the car is.

Friction is the force that opposes the tyre rubber from sliding on the road surface. Thrust is the force pushing the car forwards. There is no relative motion.

What is the maximum speed at which a car can safely travel if the radius of the track is 800 m and the coefficient of friction is 040. What is the maximum speed at which a car can safely travel if the radius of the track is. The centripetal force causing the car to turn in a circular path is due to friction between the tires and the road.

So the frictional force varies as needed up to the maximum to keep the car from slipping and for circular motion the frictional force provides the centripetal force and has value mv2r. Friction provides the force needed for a car to travel around a flat circular race track. But if the road is bank erred that means incline friction may not be required at old then what then supplies the needed centripetal force.

So for this problem we are told that friction is needed for a car rounding a curve. New statistics Pictures Argumentation Logic. We need to equal the friction force and the centripetal force.

No if we have what we can do first is to draw that situation. What is the maximum speed at which a car can safely travel if the radius of the track is 770 m and the coefficient of friction is 036. N is the normal force N mg μ is the coefficient of friction 042 ac is the centripetal force a_cv2R I.

Friction provides the force needed for a car to travel around a flat circular. See the answer See the answer done loading. What is the maximum speed at which a car can safely travel if the radius of the track is 800m and the coefficient of friction is 040.

The centripetal force is not a basic force such as friction gravity or tension in a string it is the name given to a basic force when that force maintains circular motion at constant. Similarly as you drive assuming that the wheels dont spin your wheels are pushing backwards against the floor and friction is the opposing force that pushes your wheel forward enabling you to drive forward. Example What must be the coefficient of friction between the tires and the level roadway to allow a car to make a curve of radius r 350 m at a speed of 80 kmh.

Part a for typical rubber-on-concrete friction what is the shortest time in which a car could accelerate from 0 to 60 mph. The forces acting on a moving car are thrust and drag as well as the same forces that act on a stationary car. The wheels are free to roll forward or backward.

Answer 18 m s View Answer Discussion You must be signed in to discuss. Friction provides the force needed for a car to travel around a flat circular race track. What is the maximum speed at which a car can.

V 1737 ms. A car of mass 1500kg takes a turn of a curved road of radius 300m with a speed of 9ms. For a level curve the force of friction is the only horizontal force on a car and provides the centripetal force.

This can be seen from the free-body diagram. Physics A 950-kg race car can drive around an unbanked turn at a maximum speed of 46 ms without slipping. What is the maximum speed at which a car can safely travel if the radius of the track is 800 m and the coefficient of friction is 040.

Thrust comes from the engine turning the wheels. This is the best answer based on feedback and ratings. Simply put when driving the engine generates a force on the driving wheels that moves the vehicle onwards.

Friction provides the force needed for a car to travel around a flat circular race track. How do Wheels make a Car. Static friction is what enables you to hold objects without it slipping away from your fingers.

It can be calculated by balancing the centripetal force and the gravitational force acting on it as. Watch More Solved Questions in Chapter 6. Explanation Verified Reveal next step Reveal all steps Create a free account to see explanations.

What is the maximum speed at which a car can safely travel if the radius of the track is 800 m and the coefficient of friction is 040. A ball on the end of a string is cleverly revolved at a uniform rate in a vertical circle of radius 850 cm. What is the maximum speed at which a car can safely travel if the radius of the track is 800 m and the coefficient of friction is 040.

You may want to review pages 138 - 142. Previous What does a strong conclusion do. Accordingly little or no static friction is needed parallel to the cars motion to prevent slippage fore and aft.

Correct answer to the question Friction provides the force needed for a car to travel around a flat circular race track. This car on level ground is moving away and turning to the left. The net force must be horizontal--pointing toward the center of the.

So we have a bank path and we have our card in here. So the maximum speed of the car is 1737 ms. The contact patch is not slipping.

It is friction that provides the force for a car to accelerate so for high-performance cars the factor that limits acceleration isnt the engine. Correct answer - Friction provides the force needed for a car to travel around a flat circular race track. Friction provides the force needed for a car to travel around a flat circular race track.

Drag is the force of air resistance a form of friction pushing against the front of the car while it is moving.
