Solve problem step by step
The main purpose of an air bag is to stop a passenger during a car
accident in a greater amount of time than if the air bag were not
present. For example, consider a 57 kg person traveling at 22 m/s
(about 49 mph). Use impulse and momentum to calculate how many
newtons of force would be required to stop the person in 0.037 s,
0.074 s, and 0.37 s. Note how the force changes with increased
time. (Enter the magnitudes.)
(a) How much force is needed to stop the person in 0.037 seconds?
Answer: ______N
(b) How much force is needed to stop the person in 0.074 seconds?
Answer:______N
(c) How much force is needed to stop the person in 0.37 seconds?
Answer:______N
