12. Two cars of the same mass run head-on into each other at C. After the collision, brakes locked and come to a stop in the positions shown in the lower part of the figure. Knowing that the speed of car A just before impact was 5 mi/h and that the cars skid with their the coefficient of kinetic friction 3 ft between the pavement and the tires of both cars is 0.30, determine 12 ft B just (a) the impact, speed of car before (b) the effective coefficient of restitution between the two cars.
