You have been called in by your neighborhood safety council to advise them about installing a barrier on a dangerous curve that has been subject to several recent accidents. They need to decide between a new a "softer barrier", which consists of barrels of water, and the traditional concrete barrier. In a test, two 1400 kg cars initially travelling at 50 mph were crashed into each barrier. The softer barrier took 1.6 s to bring the car to a rest, while the traditional barrier took 0.1. You have been asked to prepare a report on the force exerted on the car in each case.
