Problem Statement
Along with airbags, seat belts are not perfected life saving devices in the event of a car crash. Although these devices have greatly decreased death tolls, they still cause bodily harm due to the abrupt stop of momentum followed by the impact of the airbag.
Calculated Proof of Theory
Kinetic Energy Equation: Favg (distance) = (1/2) mv2
Impulse Equation: Favg Δt = mΔv
Weight of Person: 160lbs - Speed: 30mph - Stopping Distance: 1ft
FORCE OF NONSTRETCHING SEATBELT:
Solve for F: F= [(mv^2)/(2d)]
Convert to SI Units:
Weight of Person: 72.5748 kg
Speed: 13.4112 m/s
Stopping Distance: 0.3048m
Plug and Solve: F = 21413 N
~ 30 G
Time using Impulse: Δt= ~0.0454s
