A \(1000\,\text{kg}\) car is traveling east at \(20\,\text{m/s}\) when it collides perfectly inelastically with a northbound \(2000\,\text{kg}\) car traveling at \(15\,\text{m/s}\). If the coefficient of kinetic friction is \(0.9\), how far, and at what angle do the two cars skid before coming to a stop?
