Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

Why are NASCAR tracks banked, angled up, on the curves?

a) A banked track provides a normal force to supplement friction as a radial force.

b) Banking reduces the amount of static friction necessary between the tires and the track at a particular speed.

c) A banked curve allows cars to safely drive faster than an unbanked curve.

d) All of the above is correct

Please explain answer

Definition Definition Force that opposes motion when the surface of one item rubs against the surface of another. The unit of force of friction is same as the unit of force.

Which of the following statements are correct? Select all correct. Question 6 options: Centripetal acceleration is the result of the sum of other forces. If an object is moving at a constant speed in a circle, then every external force must point towards the center of the circle. If the speed of an object is constant, then its acceleration must be zero. The centripetal acceleration is the same whether the object moves clockwise or counter-clockwise.

A car of mass M= 800 kgtra veling at 50.0 km/hourkm/hour enters a banked turn covered with ice. The road is banked at an angle θ and there is no friction between the road and the car's tires as shown in (Figure 1). Use g= 9.80 m/s2 throughout this problem. Now, suppose that the curve is level (θ=0) and that the ice has melted, so that there is a coefficient of static friction μ between the road and the car's tires. What is μmin, the minimum value of the coefficient of static friction between the tires and the road required to prevent the car from slipping? Assume that the car's speed is still 50.0 km/hour and that the radius of the curve is 54.1 mm .
Under good conditions, a car can travel at a maximum speed of vmax around a particular unbanked curve. In the aftermath of an ice storm, however, driving at that same speed will cause the car to slide off the road. Which of the statements below best describes why this is true? a. The friction force is no longer strong enough to balance the centripetal force and give the car zero acceleration. b. The friction force is needed to do negative work on the car to reduce the car’s kinetic energy. c. The friction force no longer provides a strong enough unbalanced force to change the car’s velocity quickly enough to stay on the curve. d. The car “floats” on the ice reducing the gravitational force which is what keeps the car on the road. e. [All of the above.]
A car of mass M = 1400 kg traveling at 40.0 km/hour enters a banked turn covered with ice. The road is banked at an angle, and there is no friction between the road and the car's tires as shown in (Figure 1). Use g = 9.80 m/s2 throughout this problem. Now, suppose that the curve is level (θ=0) and that the ice has melted, so that there is a coefficient of static friction μ between the road and the car's tires as shown in (Figure 2). What is μmin, the minimum value of the coefficient of static friction between the tires and the road required to prevent the car from slipping? Assume that the car's speed is still 40.0 km/hour and that the radius of the curve is 34.6 mm . Express your answer numerically.
