Recently, several cars in the local neighborhood Winding Hillshave lost control and fallen from the road into a lake below. Thehomeowner’s association has asked for your advice regarding a planto install a barrier at the site of the frequent accidents to keepcars from falling into the lake. The barrier company has providedthe HOA with a variety of potential materials to make the barrierfrom. One member of the HOA, Sal, has recommended selecting thecheapest barrier material because he remembers from his physicsclass long ago that impulse is equal to change in momentum, so thetype of barrier will not affect the force the driver feels. Use theequipment provided to conduct experiments with various bumpers todefend or refute Sal’s claim. Answer the following questions todesign your experiment and analysis.
A. What are Sal’s claims? B. Why do airbags reduce injury in carcollisions? C. What should stay the same in your experiment as youexplore different barriers?
D.What parts, if any, of Sal’s arguments were supported orrefuted?
