Answer: 355.66 m/s
Explanation:
Since sound is a mechanical wave, its speed varies with the medium and its properties, such as its temperature.
So, if we want to calculate the speed of sound in air at we can use the following equation that relates with the temperature:
(1)
Where:
is the Heat capacity ratio for air
is the Universal Gas constant
is the air temperature in Kelvin
is the air molar mass
(2)
Finally:
This is the speed of sound at 313 K
Answer:
M1u1+(-m2u2) = (m1+m2) V. By using this equation you can find the final velocity of that. It would be 3.13ms-1. And the direction is right side.
S = d/t
s = 1396/4 = 349m/s
