Momentum is described as the result of the calculation of mass multiplied by that thing's velocity.
<span>
In equational formula we can write it: </span>
<span>
P (momentum) = m(mass) * v(velocity) </span>
so to find the mass, revert the equation:
<span>
P = m v </span>
m = P / v
now for the value entry,
<span>
m = 2.5 * 10^4 kgm/s / 30 m/s </span>
<span>
m = 8,3 * 10^2 kilograms

Explanation:
Sound waves travel at 343 m/s through the air and faster through liquids and solids. The waves transfer energy from the source of the sound, e.g. a drum, to its surroundings. Your ear detects sound waves when vibrating air particles cause your eardrum to vibrate. The bigger the vibrations the louder the sound.
Hope this helps!
