A car is traveling at 60.0 mph when
it collides with a stone wall. The car
comes to rest after the first foot of
the car is crushed. What was the
average horizontal force acting on a
150-lb driver while the car came to
rest? If five cardboard boxes, each 4
ft 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?
