S6. In their investigation at the scene of an automobile accident, the police find that car A left skid marks 45.7 m long before it collided with car B, which was at rest at a stoplight. The lea coefficient of kinetic friction between the rubber tires and the pavement at the scene of the accident is 0.60. To prove that car A was traveling over the posted speed limit of 45 mph, you calculate the minimum speed car A had just prior to the accident is: wizsoong ziri gnimub 91613 LOONE- A LOOTA- .8 10082-0 (Note: 1 m/s = 2.237 mph) A. 64 mph B. 58 mph C. 61 mph 0.8 D. 52 mph E. 55 mph hd/s C OE 1 LOOEDI- .0 0195 3
