A car of length L = 26 m is moving through the stationary air with a constant velocity V, see the picture below. At the middle of the car there is a source of sound S, which emits signals in all directions, there are also two sound detectors DL and DR at the car's edges. Which of the detectors will receive the signal earlier? left-edge detector S DL What is the speed of the car if one detector receives signals by 4 msec earlier than the other one? The air temperature is 18°C. The speed of the car, V = 342.25413 x Units m/s DR Now the car is stationary but there is a 18-m/s wind blowing towards the car, as shown below. Which of the detectors will receive the sound signal earlier? left-edge detector S D₁ Units ms DR wind What is the time difference in the signal detection between the left and right detectors? The time difference, At =

Standing at the base of one of the cliffs of Mt. Arapiles in Victoria, Australia, a hiker hears a rock break loose from a height of 105.0 in. He can’t see the rock right away, but then does, 1.50 s later. (a) How far above the hiker is the rock when he can hear it? (b) How much time does he have to move before the rock hits his head?
On February 15, 2013, a superbolide meteor (brighter than the Sun) entered Earth’s atmosphere over Chelyabinsk, Russia, and exploded at an altitude of 23.5 km. Eyewitnesses could feel the intense heat from the fireball, and the blast wave from the explosion blew out windows in buildings. The blast wave took approximately 2 minutes 30 seconds to reach ground level. (a) What was the average velocity of the blast wave? b) Compare this with the speed of sound, which is 343 m/s at sea level.
