I'm going to assume that the 10.97 km/s is the velocity at the end of the cannon.
vi = 0
d = 220m
vf = 10.97 km/s = 10970 m/s
a = ???
vf^2 = vi^2 + 2*a*d
10970^2 = 0 + 2*a*220
10970^2 / 440 = a You are right this is a pretty big number.
2.73 * 10^5 = a
Answer:
The human ear is not sensitive to every frequency of sound, rather, our hearing range is from 20Hz to 20,000Hz. This means sound frequencies outside this range are not audible to the human ear, which is why not every sound produced is heard. This is quite a blessing because if we could hear every vibrating body, then our ears would never stop listening: we won't be able to distinguish 'important sounds' from unimportant ones, rendering our ears effectively useless. Perhaps this is why we have a hearing range in the first place: sounds of our friends and our foes lie in 20Hz-20kHz range.
100m ÷ 50s = 2m/s
Just some simple divison.
Answer:
<u><em>on flow properties and free-flowing and cohesive. </em></u>
