Question
Recently, several cars in the local neighborhood Winding Hills have lost control and fallen from the road into a lake below. The homeowneres association has asked for your advice regarding a plan to install a barrier at the side of the frequent accidents to keep cars from falling into the lake. The barrier company has provided the HOA with a variety of potential materials to make the barrier from. One member of the HOA, Sal, has recommended selecting the cheapest barrier matieral because he remembers from his physics class long ago that impulse is equal to change in momentum, so the type of barrier will not affect the force the driver feels. Use the equipments provided to comduct experiments with various bumpers to defend or refute sals claim. Question: 1. Why do airbags reduce injury during car collisions? 2. What should stay the same in your experiment as you explore different barriers?
Explanation / Answer
Impulsive force is the force that acts in a short duration of time. Air bags increases the time of contact . That means the collision time increases, Hence, the effect of impulsive force decreases and hence there is a reduction in injury during collsisions.
Though we use diffrent barriers, the time of contanct must remain same.
