Question
A student proposes a design for an auto-mobile crash barrier in which a
1700-kg sport utility vehicle moving at 20 m/s crashes into a spring of
negligible mass that slows it to a stop. So that the passengers are not
injured, the acceleration of the vehicle as it slows can be.no greater than
5.00g. Find the distance (in m) the spring will compress in slowing the
vehicle to a stop. In your calculation, disregard any deformation or
1 p
crumpling of the vehicle and the friction between the vehicle and the
ground. *
