A person in a car during a sudden stop can experience potentially serious chest injuries if the combined force exerted by the seat belt and shoulder strap exceeds 16,000 N. Assume the mass of passenger is 80 kg and initial speed of car is 16 m/s.
Part A. Determine required minimum stopping time interval to avoid injury. Express your answer to two significant figures and include the appropriate units.
Part B. Determine the corresponding stopping distance. Express your answer to two significant figures and include the appropriate units.
