(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

An object moving on the x axis with a constant acceleration increases its x coordinate

by 31 m in a time of 6.4 s and has a velocity

of 20 m/s at the end of this time.

Determine the acceleration of the object

during this motion.

2. Relevant equations

v=vi+at

V^2=Vi^2+2ax

3. The attempt at a solution

What I did:

found the initial velocity by dividing 31m/6.4s and got 4.84375

used galileo's formula: V^2=Vi^2+2ax

my answer was 6.3 or so and it was wrong

I am not so sure that the initial velocity is right, but I cannot think of any ideas. Can someone assist me in the right direction?
