a car crash in which people are killed or hospitalised—for cars travelling at or above 60 km/h. They found that the risk approximately doubled for every 5 km/h above 60 km/h. Thus, a car travelling at 65 km/h was twice as likely to be involved in a casualty crash as one travelling at 60 km/h. For a car travelling at 70 km/h the risk increased fourfold. For speeds below 60 km/h the likelihood of a fatal crash can be expected to be correspondingly reduced. If, instead of hitting a pedestrian, the car hits a tree, a brick wall, or some other heavy object, then the car’s energy of motion (kinetic energy) is all dissipated when the car body is bent and smashed. Since the kinetic energy (KE) is given by KE=(1/2) mass × speed2 it increases as the …show more content…

Ever since the airbag was created it has decreased deaths by 24%, it only takes 40 milliseconds for the airbag to deflate, it works by when the crash sensor in the airbag detects a collision it send an electrical shock to the inflator that which inflate the airbag, it expands rapidly because inside the airbag chamber it is equipped with nitrogen gas which expand faster than oxygen. The airbag was invented by John W hetrick in 1952, the companies that were battling to make the airbags where General Motor and Ford, GM made the first working airbag of the century, they then decided to put airbags in 100,000 cars, but eventually because GM didn 't sell many the idea of airbags in cars died until Mercedes benz put airbags in their 1984 models, in 1990 the US decided to pass a law saying all cars sold in the US need to be equipped with an airbag. Newton 's first law of motion: the law states that “Any object at rest remains at rest, and any object in motion remains in motion unless an outside force is
