The Speed of Sound Calculation on the Day of an Experimental Rocket Car Explosion

Background Information

An experimental rocket car moves along a straight track at a constant speed of 90.0 m/s. The car passes a group of officials, travels a distance of 270.0 m, and then explodes. If the officials hear the sound of the explosion 3.8 s after the car passes their position, what is the speed of sound on that day?

Calculation and Final Answer

The speed of sound on the day of the explosion is approximately 71.05 m/s.

Explanation

To calculate the speed of sound on the day of the explosion, we can use the formula: Speed of Sound = Distance / Time The time it took for the officials to hear the sound of the explosion is given as 3.8 seconds. We can use this time and the distance traveled by the rocket car (270.0 m) to find the speed of sound. Speed of Sound = 270.0 m / 3.8 s = 71.05 m/s Therefore, the speed of sound on that day was approximately 71.05 m/s.
