I have just sumitted a maths paper and one question has given me sleepless nights and I'm after advice:
Show that x = v1 + 1/2 at2
if v2 = v1 + at and x = (v1 + v2) t-----------2
I hadn't got a clue where to even start and made a complete hash of it!
Any advice where I should of started or what I should of done would be great.
