You are watching a lightning storm through your window. You see a big flash of light and you start counting the seconds: one potato, two potatoes, three potatoes... You hear loud thunder when you are at 13 in your counting. If sound travels one kilometer in three seconds, then how far is the storm from you? You can get a pretty good approximation of the distance in miles, if you assume that sound travels one mile in five seconds. What...

There is a delay from the time someone sees a flash of lightning to the time that thunder is heard due to the time it takes for sound to travel from where the lightning struck to where you are when you hear the thunder. If you hear thunder 13.6 seconds after seeing the lightning, how far away did the lightning bolt strike? Take the speed of sound in air to be 343 m/s. Answer in metres.
At room temperature, sound travels at a speed of about 344 m/s in air. You see...
At room temperature, sound travels at a speed of about 344 m/s in air. You see a distant flash of lightning and hear the thunder arrive 7.8 seconds later. How many miles away was the lightning strike? (Assume the light takes essentially no time to reach you.)

problem out
It was a dark and stormy night, when suddenly you saw a flash of lightning. Six and a half seconds later you heard the thunder. Given that the speed of sound in air is about 340 m/s, how far away was the lightning bolt? (Ignore the travel time for the flash of light.)

You are hiking along a trail in a wide, dry canyon where the
outdoor temperature is T = 27° C. To determine how far you
are away from the canyon wall you yell “Hello” and hear the echo
t = 2.75 s later.

1.You are driving slowly on the highway at 50 mph when a police car with its lights flashing passes you going 100 mph. Relative to you, the police officer is moving 50 mph. Far in the future, when humans have mastered space travel, an astronaut is moving in a spaceship at half the speed of light, v = c/2, relative to earth, when a light beam sent from earth moving parallel to the spaceship passes it moving at v =...

Your friend is about to drive away after moving out and you notice that they left behind their basketball, so you decide to throw it at a 45 degree from the horizontal towards the truck. If the truck is 7.3 m away from you, at what speed must you throw the ball for it to make it into the truck? Assume you launch the ball at the same height as the truck bed. Report the value in m/s rounded to...

Alpine-Himalayan Ocean Paoiño Ocean Ocean Deep eartho EXERCISE 16.2 Locating Earthquake Epicenters Name: Course Section: Date: This exercise leads you through the reasoning used to calculate the distance from a seismic station to epicenter. But instead of two different seismic waves, let's see first how this works with two cars that start along a road at exactly the same time (see the figure on the next page). Both use cruise control set at 1 mile per minute (60 miles per...
