6.)What is the momentum of a train traveling at 0.2 ???? ???? with a mass of 100 metric ton (1t=103 kg)? 6) What is the momentum of a small car with the velocity of 3.5???? ???? and mass of 2 tonnes?

7) If the train and car (see #5 and #6) traveling in the same direction collide in a perfectly inelastic collision, what is the velocity and the momentum of the system after collision?

8) What is the total momentum if the car and train collide in an elastic collision?

9) Compare in the value of the total momentum of the system after elastic and inelastic collision in problems 7 and 8. What is the difference between elastic and perfectly inelastic collision? Explain your answers.
