How much force is exerted on a 60 kg person who hits an airbag at 45 m/s if the impact takes 0.65 seconds? give me an explanation as to how you got the answer if you can : )

The drag force, fd, imposed by the surrounding air on a vehicle moving with velocity v is given by fd = cdaρv 2/2 where cd is a constant called the drag coefficient, a is the projected frontal area of the vehicle, and ρ is the air density. an automobile is moving at v = 80 kilometers per hour with cd = 0.28, a = 2.3 m2, and ρ = 1.2 kg/m3.
