m - We have two toy rail cars. Car 1 of mass 2 kg is traveling at 3 towards the second rail car of mass 1 kg. There is a bumper on the second rail car that engages at the moment the cars hit (it connects to S N The second - two cars) and does not let go. The bumper acts like a spring of spring constant k = 2- car is 10 meters from a wall. See the following figure. 21 k ww m2 10 meters m 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?
