An sub with a mass of 1800 kg is traveling eastbound at 17 m/swhile a compact car with mass of 900 kg is traveling westbound witha speed of 15 m/s the cars collide head-on becoming entangled.
Find the speed of the entangled cars after the collision
Find the change invelocity of each car
Find the change in the kinetic energy of the system consisting of both cars.
