Your accident  reconstruction team has been hired by the local police   to analyze the following accident. A careless driver rear-ended a car that was halted at a stop sign.   Just   before impact, the   driver slammed on his brakes, locking   the wheels. The driver   of the struck car had his foot solidly on the brake pedal,   locking his brakes.   The   mass of   the   struck car was 900 kg,   and   that   the   initially moving vehicle   was   1200 kg.   On collision,  the   bumpers  of the two cars meshed. Police determine   from the   skid marks that after the collision   the   two   cars   moved 0.76 m together. Tests revealed that the   coefficient of   kinetic friction between the   tires   and   pavement was 0.92. The driver of the   moving car claims that   he was traveling at less than 15 km/h as he approached the intersection. Is he telling the truth?
