Hello I was trying to find the proof of the formula
x = x0 + v0t +.5at^2
were the zeros are subscripts
My text book dosen't explain it that well.
ok well
it involves the formula for
average velocity
aver velocity = 2^1(v0 + v)
were the zero is a subscript and this is just because if there is constant acceleration than the velocity average is between the inital and final I understand this
ok it also involves using this formula
x = x0 + average velocity(t)
which I understand the proof of how to get this formula were the zero is a subscript
ok so in my book it shwos the proof like so
x = x0 + average velocity(t)
were the zero is a subscript
then you plug in that other formula and get this
x = x0 + (2^1(v0 +v))t
were the zeros are subscripts
ok this is were I get lost
then next step in my text book shows this
x = x0 + (2^1(v0 + v0 at))t
were zeros are subscripts
ok were did the extra v0 come from?
were did the at come from?
then of course the next line
x = x0 + v0t + .5at^2
I was hopeing somebody could explain to me this proof
THANK YOU!

I FIGUERED IT OUT THANKS

Ok, good. It is kind of artificial because you are doing calculus without calculus.
