1. The problem statement, all variables and given/known data A 58 kg person is in a head-on collision. The car's speed at impact is 13 m/s. Estimate the net force on the person if he or she is wearing a seat belt and if the air bag deploys. For some reason, I can't seem to get the correct answer to this question... I have no idea where I am going wrong. According to the question, if a person is wearing a seatbelt, they deaccelerate over a distance of 1m. 2. Relevant equations (Final Velocity)^2 = (Initial Velocity)^2 + 2*acceleration*distance Force=mass*acceleration 3. The attempt at a solution First off, I had to find the deacceleration over the distance of 1m: (Final Velocity)^2 = (Initial Velocity)^2 + 2*acceleration*distance 0 = (13m/s)^2 + 2*acceleration*1m acceleration= -84.5m/s^2 Using that acceleration to calculate net force... F=ma = (58kg)(-84.5m/s^2) =-4901N I put that answer into the system and it comes back wrong... Help is appreciated. Thanks!
