The coefficient of static friction between the tires of a car and a horizontal road is 0.2. If the net force on the car is the force of static friction exerted by the road, what is the maximum acceleration of the car when it is braked? The acceleration clue to gravity is 9.81 m/s^2 . Answer in units of m/s^2. What is the shortest distance in which the car can stop if it is initially traveling at 30 m/s? Answer in units of m.
