2) A car of mass 1000kg is travelling in an eastward (+x) direction with a constant speed of 20m/s. It then hits a stationary truck. The truck is twice as heavy as the car. After the collision, the car travels in a direction 300 North of East and the truck travels 600 South of East. (a) What are the final speeds of the car and the truck after collision? (b) Calculate the change in kinetic energy of the system before and after collision. (c) Based on your answer in part (b) what type of collision do you think this is?

A car has a mass of 2000 kg which was travelling east but now has collided with truck with mass of 2500 kg which was travelling north. After the collision we see that the cars are stuck together and have slid 7.7 meters northeast at a 40 degree angle. The car driver claims the accident happened because the truck was speeding; the truck driver claims the car was speeding. The posted speed limit is 35 miles/hour. Determine from the location...
