I forgot the equation for friction F=ma * mew?? Anyway The driver of a 1560kg Toyota traveling at 24m/s hits breaks for red light. What is the distance needed to stop if the coefficient of friction is 0.80?

I'm guessing I have to use some kinematics and find the net force and divide the mass for the acceleration and use that to figure out the distance where v_f = 0 etc etc, anyway I just can't find this formula I forget. Can someone help out? I've tried google.
