The car comes to rest after the first 30 cm of the car is crushed.what was the average horizontal force acting on a 68.1 kg driver while the car came to rest? If 5 cardboard boxes each 1.25 m wide and filled with sand had been placed in front of the wall and the car moved through all that sand before coming to rest, what would the average force acting on the driver have been then?
