A 65 kg person is riding in a car moving at 16 m/s when the car runs into a concrete bridge abutment. Calculate the average force (in lbs) on the person if he is stopped by a padded dashboard that compresses an average of 0.7 cm.

Calculate the average force (in lbs) on the person if he is stopped by an air bag that compresses an average of 20 cm.
