I do not have strength to comment this gibberish.


Does not deserve any attention.

Even recycling will not help in this case.

+s+=+%28+1%2F2+%29%2Ag%2At%5EN+
+s+=+1870+ m
+t+=+12+ sec
+g+=+8.8+ m/sec2
---------------------------
+1870+=+%28+1%2F2+%29%2A8.8%2A12%5EN+
+1870+=+4.4%2A12%5EN+
+12%5EN+=+425+
+N%2Alog%28+12+%29+=+log%28+425+%29+
+N%2A1.07918+=+2.6284+
+N+=+2.4355+
------------------------
check:
+1870+=+%28+1%2F2+%29%2A8.8%2A12%5EN+
+1870+=+%28+1%2F2+%29%2A8.8%2A12%5E2.4355+
+1870+=+4.4%2A424.958+
+1870+=+1869.81+
error due to rounding off, I think
