## Homework Statement

**On May 19, an accident occurred at the corner of two asphalt streets with no stop signs. The speed limit was 40 km/h on both streets. As lead CSI on the case, you must determine whether one or both cars should be ticketed for speeding, which car had right of way at the intersection, and whether one driver or both were at fault for the accident.**

Using data tables, you have determined that the mass of car A is 2275 kg and the mass of car B is 1525 kg. You measured the skid marks when the cars were locked together and found that they were 3.705 m long at an angle of 47 degrees east of the northbound street. Witness accounts put both cars 5 m from the intersection at the same time. The coefficient of kinetic friction b/w rubber and asphalt is 0.80. The rules of the road at an intersection w/o stop signs is that if 2 cars get to the intersection at the same time, the right-hand car has right of way.
