At the scene of an accident, two traffic experts appear to determine which of the drivers was at fault considering that it was a highway where the speed limit is 80 km / h. The data collected in the field indicate that the vehicles stuck and skidded together a length of 25 m on the pavement whose dynamic friction coefficient is μk = 0.30. Considering that the masses of vehicles A and B are 2300 kg and 1500 kg, respectively, specify which of the cars was speeding at the moment of impact and by how much it exceeded the speed limit. Express your result in km / h for the purposes of the expertise.
