Homework Statement
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? ? ?
Homework Equations
kinetic friction = (coefficient of kinetic friction)( Normal force)
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
