Your neighborhood safety council wants you 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 "softer barrier", which consists of barrels of water, and the traditional concrete barrier. in a test, two 1800 kg cars initially travelling at 25m/s crashed into each barrier. the car that struck the soft barrier was brought to rest in 2.1 s. the car that struck the traditional barrier was brought to rest in 0.08 s.
prepare a brief numerical statement on the force felt by each occupant using the test information provided.
