(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

On a level road with its brakes on, a car traveling at 86 km/hr stops within 93 m when the brakes lock and the car slides.

- a) What is the magnitude of the acceleration of the car? 3.0967 which i already found.

- b) What is the coefficient of kinetic friction between the tires and the pavement? ? ?

2. Relevant equations

kinetic friction = (coefficient of kinetic friction)( Normal force)

3. The attempt at a solution

For part B (the part i can't figure out)

86km/hr = 24m/s

24(9.8 gravity)= 235.2 Normal force

24/235.2 = .102 = coefficient of kinetic friction which is wrong
