1. For example. If you weigh 175lbs and you were running into a wood fence at 7km/per hour how much force is being applied the Wood fence? Another Example. the TGV Train in France reached its highest speed at 574km/per hour it weighs 415tons, if this train were to collide with an abandon car on the tracks how much force would be applied to the abandon car on the tracks if the train were going 570km/per Hour and the Train weighs 415tons (914,918lbs). another example: A freight Train weighing 10,000 tons going at a speed of 50km/per hour were to hit an abandon car how much force is being applied to the car on the tracks? The distance of the Fence is 40ft. The distance of the Car is 100ft.
