The problem involves a car with a mass of 1250 kg that comes to a stop from a speed of 60.0 km/h over a distance of 35 m. The goal is to determine the coefficient of friction acting on the brakes, with a focus on finding the car's acceleration.
The discussion is ongoing, with participants exploring different approaches to find the necessary equations and calculations. Some guidance has been offered regarding the use of kinematic equations and the concept of average velocity, but no consensus has been reached yet.
One participant notes the absence of a list of formulas for constant accelerated motion, which may limit the discussion. The original poster expresses confusion regarding the information provided and seeks assistance.
As Delphi51 said, you could use one of the kinematic equations.anikam said:Homework Statement

The Attempt at a Solution
I'm stumped on how to figure out the acceleration of the car as they only give you the mass, distance, and final velocity. Can anybody help me? Thanksss!
