how would i do this...(adsbygoogle = window.adsbygoogle || []).push({});

A particle moving along the x-axis has its position described by the function x=( 2.00 t^{3}- 5.00 t+ 1.00 )\; {\rm m}, where t is in s. At t= 4.00 , what are the particle's position- i calculated that to be 109m , velocity, and acceleration?

i have tried for over an hour on this one problem. i am clueless. my physics book sucks!
