INTRODUCTION: This is a problem from my Introduction to Physical Science class using "Conceptual Physics" 10th Ed.by Paul G. Hewitt EXACT PROBLEM: "The coefficient of kinetic friction between a rubber tire and a wet concrete road is 0.5." PROBLEMS FACED: a) Find the minimum time in which a car whose initial speed is 30 mi/hr can come to a stop on such a road. b) What distance will the car cover in this time? MY THOUGHTS: I know I have a coefficient of friction & V0 and Vf. Beyond that, I don't know how to look for the time it will take. What equation am I supposed to be using?
