The coefficient of friction between the tires of Shirley's 1985 Ford Coupe and the dry pavement is 0.74. She doesn't drive the car often because it's becoming an antique, but she took it out for a gentle drive yesterday. While driving, she has to suddenly and forcefully brake when the light turned red. She probably shouldn't have been texting and driving! Her car (mass = 1.31x10³ kg) skids to a stop with an acceleration of m/s². Use the approximation g = 10 m/s².
