Question

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? Please give me an explanation as to how you got the answer if you can :)

Answer 1

We must rewrite the Newton's Second Law:


`F_(av)=ma_(av)~~~~`

Applying in the question:


`F=60( (45)/(0.65) ) \\ \boxed {F \approx 4.15~kN}`
