Airplane flight recorders must be able to survive catastrophic crashes. Therefore, they are typically encased in crash-resistant steel or titanium boxes that are subjected to rigorous testing. One of the tests is an impact shock test, in which the box must survive being thrown at high speeds against a barrier. A 43-kg box is thrown at a speed of 340 m/s and is brought to a halt in a collision that lasts for a time of 6.6 ms. What is the magnitude of the average net force that acts on the box during the collision?
Because of your knowledge of physics, you have been assigned to investigate a train wreck between a fast moving passenger train and a slower moving freight train both going in the same direction. You have statements from the engineer of each train and the stationmaster, as well as some measurements you make. To check the consistency of the description of events leading up to the collision, you decide to calculate the distance from the station that the collision should have occurred if everyone’s statements were accurate. You will then compare that result to the actual position of the wreck that is 0.5 miles from the station. In this calculation you decide that you can ignore all reactiontimes. Here is what you know: • The stationmaster claims that she noted that the freight train was behind schedule. As regulations require, she switched on a warning light just as the last car of the freight train passed her. • The freight train engineer says he was going at a constant speed of 10 miles…
