Q. Two speakers, one directly behind the other, are each generating a 376-Hz sound wave. What is the smallest separation distance between the speakers that will produce destructive interference at a listener standing in front of them? Take the speed of sound to be 343 m/s.
Q. A 3000 pound car crashes into a concrete jersey barrier moving 3 sections (totaling 12,000 pounds) laterally 24 inches. How fast was the car going on impact?
