What more can I say that I have been extremly busy, tests and so on.
And to top that... I got a very hard math problem (for me). And it took a lot of time to solve it. But with help, I have now finally solved it. Hurray!
Here was my problem:
Question:
"Alexandra drops a stone down a well. After a while she can hear the stone hit the bottom. How deep is the well, if you neglect the air resistance, but regard the speed of sound?"
g=9,82m/s^2
v=331m/s
Answer:
s=(t*331+331^2/9,82)-sqrt(331^4/9,82^2+2t*331^3/9,82)
Well I got a test on tuesday, so don't expect to see so much of me until then.
BQ out.
