## Homework Statement

A particle moves along a straight line such that its acceleration is a = (4t

^{2}-2) [itex]\frac{m}{s^2}[/itex], where t is in seconds. When t = 0, the particle is located 1 m to the left of the origin, and when t = 2 s, it is 20 m to the left of the origin. Determine the position of the particle when t = 4.3s.

**2. Homework Equations &**

**The attempt at a solution.**I am just stuck on this. I know I should already know how to do this but right now my mind is blank!

I know that I can get the velocity equation by integrating, but when I try to use t=2 s, and then using the equation x=x

_{o}+v

_{o}t+[itex]\frac{1}{2}[/itex]at

^{2}, I am not even close to the x=20.
