A 2210 kg car traveling at 10.1 m/s collides with a 2680 kg car that is initally at rest at a stoplight. The cars stick together and move 2.10 m before friction causes them to stop. Determine the coefficient of kinetic friction between the cars and the road, assuming that the negative acceleration is constant and all wheels on both cars lock at the time of impact.
