HELP Friction on Ice involving weight

In summary, a car with a mass of 2580.0 kg and a constant speed of 14.0 m/s on an icy, level road comes to a stop in 26.4 m after the driver slams on the brakes. The acceleration is -0.5303 and the coefficient of kinetic friction between the tires and the icy road can be found using the equation Ffriction = ma = μW = μmg.

You are driving a 2580.0 kg car at a constant speed of 14.0 m/s along an icy, but straight, level road. As you approach an intersection, the traffic light turns red. You slam on the brakes. Your wheels lock, the tires begin skidding, and the car slides to a halt in a distance of 26.4 m. What is the coefficient of kinetic friction between your tires and the icy road.



The Attempt at a Solution


I found the acceleration to be -.5303 by taking -14/26.4 (v=v0+at) but now I'm confused as how to find the kinetic friction by stopping

Find the acceleration or deceleration, then

a/g = [itex]\mu[/itex], since Ffriction = ma = [itex]\mu[/itex] W = [itex]\mu[/itex]mg.

im sorry man still not getting it, is there some sort of website that has all the equations on it?
 

FAQ: HELP Friction on Ice involving weight

What is friction on ice?

Friction on ice refers to the resistance force that occurs when two objects rub against each other on an icy surface. This force can be caused by the weight and type of object, as well as the smoothness of the ice surface.

How does weight affect friction on ice?

The weight of an object can significantly impact the amount of friction on ice. The heavier the object, the more force it will exert on the ice, increasing the amount of friction. This is because the weight of an object creates a larger normal force, which is the force that pushes the two surfaces together.

What factors affect friction on ice?

Aside from weight, other factors that can affect friction on ice include the type of object (such as the material and shape), the speed at which the object is moving, and the temperature and texture of the ice surface.

How can friction on ice be reduced?

There are a few ways to reduce friction on ice, such as using a lubricant (like salt or sand), changing the shape of the object, or decreasing the weight of the object. Additionally, increasing the speed of the object can also reduce the amount of friction on ice.

Why is friction on ice important?

Understanding friction on ice is important for several reasons. It can help us predict and prevent accidents on icy surfaces, improve the design of ice skates and other equipment used on ice, and aid in the development of new materials and technologies for better performance on icy surfaces.
