Two cars collide at right angles and stick together as they skid to a stop. Car 1 has a mass of 1300 kg and a speed of 21 km/h to the east. Car 2 has a mass of 1000 kg and a speed of 36 km/h to the north. The average coefficient of friction between the tires and the road is 0.65. How far from the collision point, and in what direction, do the cars stop?
