## Homework Statement

I took this right out of the text, it is not home work just me trying to get better.

The acceleration of a particle is defined by the relation a = -8 m/s^2

Knowing that x = 20 m when t= 4 m, and that x = 4 m when v = 16 m/s

(a) determine the time when velocity is zero and (b) the velocity and total distance traveled when t = 11 s

## Homework Equations

## The Attempt at a Solution

My attempt is I know velocity must be the integration of acceleration and displacement the integration of velocity. So I attempted to integrate -8dt 2 times. but when I do that I get x=-4t^2 which does not fit my given when t=4, x=20

Any help would be greatly appreciated, even just pointing me in the right direction
