A designer proposes a design for an automobile crash barrier in which a 1200 kg car moving at 20 `m//s` crashes into a spring of negligible mass that slows the car to a stop. To avoid injuring the passengers, the acceleration of the car as it slow can be no more than 5 g find the required spring constant and find the distance the spring will compress slowing the car to a stop
