What are the characteristics of a banked curve, and how does it affect the motion of a vehicle?
A banked curve is tilted sideways, with the outer edge higher than the inner edge. This tilt helps vehicles navigate the curve more safely and efficiently by reducing the need for friction to keep the vehicle from sliding off the road. The banking of the curve allows the vehicle to turn more smoothly and at higher speeds without skidding.
What are the key components of a free body diagram for a vehicle navigating a banked curve?
The key components of a free body diagram for a vehicle navigating a banked curve include the forces acting on the vehicle, such as gravity, normal force, friction, and centripetal force. These forces help to show how the vehicle's motion is affected by the curve and the banking angle.
How does friction affect the stability and safety of vehicles navigating banked curves?
Friction plays a crucial role in the stability and safety of vehicles navigating banked curves. It helps to keep the vehicle from sliding off the curve by providing the necessary grip between the tires and the road surface. Without enough friction, the vehicle may lose control and skid off the curve, leading to potential accidents. Therefore, sufficient friction is essential for maintaining stability and ensuring safety while navigating banked curves.
How does the banking of a curve affect a car's performance when taking a banked curve?
When a car drives on a banked curve, the banking of the curve helps to counteract the force of gravity pulling the car outward. This allows the car to maintain better traction and stability, resulting in improved performance and speed through the curve.
The maximum speed at which a car can safely negotiate a frictionless banked curve depends on all of the following except?
The maximum speed at which a car can safely negotiate a frictionless banked curve does not depend on the mass of the car. It depends on the angle of the bank, the radius of the curve, and the coefficient of static friction between the tires and the road surface.

Physics coefficient of friction radius of 60 m is properly banked for a car traveling 60 kmh what must be the coefficient of static friction for a car not to skid when travelling at?
The coefficient of static friction for a car not to skid when travelling at 60 km/hr on a banked curve of radius 60 m is 0.25. This is calculated using the formula: coefficient of static friction = tan(θ), where θ is the angle of banking. Given that the equation is properly banked, the angle of banking would be such that tan(θ) = V^2 / (R * g), where V is the velocity, R is the radius of the curve, and g is the acceleration due to gravity. Substituting the values, we get tan(θ) = (60 km/hr)^2 / (60 m * 9.8 m/s^2) = 0.25.
If a curve with a radius of 60 m is properly banked for a car traveling 60 kmh what must be the coefficient of static friction for a car not to skid when travelling at 90 kmh?
To prevent skidding at 90 km/h, the car would need a coefficient of static friction of at least 0.25. This value can be calculated using the formula: coefficient of friction = tan(theta), where theta is the angle of banking. Given the curve radius, speed, and the formula, we can determine the necessary value for the coefficient of friction.
Which force is responsible for holding a car in a frictionless banked curve?
The Horizontal Component of the normal force.
When a railroad train rounds a banked track the centripetal force needed comes not from friction but from the?
centripetal force needed to keep a train on a banked track comes from the component of the train's weight that acts perpendicular to the track surface. This force is provided by the normal force exerted by the track on the train, which is greatest on the outer edge of the curve. Friction plays a role in providing the lateral force that counteracts the inward acceleration.
