Car A (with a mass of 2500 kg), trying to pass a slower car, collies head on with Car B (with a mass of 1000 kg). Car B was travelling west at an initial speed of 30 m/s before the collision. They stick together and skid another 5 m to the east. What was Car A’s initial speed if it skids 10 m before the collision?

Was the driver of Car A or Car B speeding? Who was at fault in the collision and why?
