17. Two cars collide and then ricochet off each other in opposite directions. Car 1, with a mass of 250 kg, goes to the right with initial velocity of 2 m/s. Car 2, with a mass of 350 kg, moves to the left with an initial velocity of -2.30 m/s. After the collision, car 1 recoils a velocity of -3.00 m/s. What is the final velocity of the car 2? 18. Refer to item #17. What is the kinetic energy of Car 1 after the collision? 19. Refer to item #17. What is the kinetic energy of Car 2 before the collision? 20. Refer to item #17. If the two cars stick together after the collision, is the kinetic energy conserved? Explain your answer.
