Police are investigating a collision between two cars. A 1900 kg car was initially travelling east and a 1300 kg car was initially travelling south. From the skid marks on the ground and using information about the friction between the tires and the road surface, police investigators have determined that the cars became locked together and had a velocity of 32 km/h [E39°S] after the collision. If the posted speed limit on both streets was 40 km/
