Coefficient of sliding friction for car braking on ice

[halo9909]

Homework Statement

You are driving a 2410.0-kg car at a constant speed of 11.0 m/s along an icy, but straight and level road. While approaching a traffic light, it 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 29.0 m. What is the coefficient of sliding friction (µ) between your tires and the icy roadbed?

m=2410kg
vi=11m/s
vf=0m/s
d=29meter

Homework Equations

µ=F/N?

The Attempt at a Solution

i first did 2410kg * 9.8 =23618N so that would be the force normal, from there I dnt know how to get the force of friction

They give you the initial and final velocity, and the displacement. What kinematic quantity can you find using those values that would be helpful in finding a force?
