SUMMARY
The discussion focuses on calculating the deceleration of a 75 kg dummy during a crash when an airbag inflates, exerting a net force of 825 N in the opposite direction of motion. Using Newton's second law, F = ma, the deceleration can be determined by rearranging the formula to a = F/m. Substituting the given values, the deceleration is calculated as 11 m/s². This demonstrates the effectiveness of airbags in reducing the forward motion of occupants during a collision.
