Cars today have three-point seatbelts where one strap goes across the waist and another goes
across the body; these seatbelts are effective at the speeds at which cars travel. However,
fighter jets travel at much faster speeds, about 20 times faster than a commercial car nese
fighter jets accelerate so quickly that fighter pilots need to be strapped in more tightly. Do you
believe that these three-point seatbelts would be effective for pilots in a fighter jet? Evaluate
the problems the pilots might have with a three-point seatbelt by explaining the forces acting
on the pilot. Define the criteria and constraints for the problem.
