Contradiction in the equations of motion...??!
I' ve found a strange contradiction between the fist and second equations of motion. First we start with the second equation:
s = ut + 1/2at2
We factor 't' out, whoch gives us:
s = t(u + 1/2at)
We divide both sides by 't', and on the LHS we get 's/t' which should be equal to 'v', i.e., the velocity:
v = u + 1/2at
But, the first equation goes as the following:
v = u + at
And that contradicts our previous result...but...how??!
