Problem
A 65kg stunt performer steps off a platform 4.0m above a large airbag. The airbag brings the performer to rest uniformly in 0.40s after first contact. Neglecting air resistance during the fall and assuming the gravitational force during the brief impact interval is negligible compared with the airbag’s force, determine the magnitude of the average force exerted by the airbag on the performer while stopping her.
