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?
Two cars with equal mass collide head on. One car is going 18 mph. That car is push backward about 38 feet. What is the speed of other vehicle.
100 g ball of clay is thrown horizontally with a speed of 13m/s toward a 900g block resting on a frictionless surface. It hits the block and sticks. The clay exerts a constant force on the block during the 7 ms it takes the clay to come to rest re..
A hiker's trip consists of three segments. Path A is 7.00 km long heading 60.00 degrees north of east. Path B is 6.00 km long in the direction due east. Path C is 5.00 km long heading 315 degrees counter clockwise from east. Graphically add hiker's d..
