I think you can do it a bit easier by just using the general formula:
$$s(t)=s_0+v_0t+\frac{1}{2}at^2$$, and just filling in the information given in the question.

anonymous · Answer

Hmm, never been introduced to that formula. o-o

anonymous · Answer

It might look more familiar in the form:$$s=ut+\frac{1}{2}at^2$$

anonymous · Answer

Emm, we ended up with s(t)= -cos(4t)+2t+6  ...

anonymous · Answer

The other method is correct as far as I can tell. Not sure what to tell you!

anonymous · Answer

What did you get with the other method?

anonymous · Answer

I think my formula may only work for constant acceleration now that I think about it. By 'the other method', I mean the one used by Mr. Math and yourself in http://openstudy.com/#/updates/4edd38aae4b01b4ec492d3d1

Aaaah, okay. Either way, thanks. :]
