A 1890 kg car traveling at 13.3 m/s collides with a 2970 kg car
that is initally at rest at a stoplight. The cars stick together
and move 1.96 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.
