Example 3.6.2 We have two toy rail cars. Car 1 of mass 2 kg is traveling at 3 towards the second rail car of mass S 1 kg. There is a bumper on the second rail car that engages at the moment the cars hit (it connects to two cars) and does not let go. The bumper acts like a spring of spring constant k =2. The second N car is 10 meters from a wall. See the following figure. Show solution 10 meters We want to ask several questions. At what time after the cars link does impact with the wall happen? What is the speed of car 2 when it hits the wall? Exercise 3.6.2 PP21 k www.mz m Suppose in Example 3.6.2 the second car is moving to the left at 3 - at the time of impact. Find the behavior of the system after linkup: S Hint At first, the second car will start moving to the left, but then it will move to the right for while. When is the next time t that the second car will start moving to the left?
