Homework Statement
An object moves with constant acceleration 4.00 m/s2 and reaches a final velocity of 12.0 m/s.
a) If its initial velocity is 6.00 m/s, find its displacement and the distance it travels
b) Same question as above instead its initial velocity is now -6.00 m/s
Homework Equations
vf2 = vi2 + 2a /\x
The Attempt at a Solution
I solve a) already and got 13.5 m as answer for both the distance and displacement. For b), the displacement is the same because plugging-in 6 or -6 doesn't change the above equation, however I don't know how to solve for the distance. I know that it will be something bigger than 13.5 m but still cannot figure out the answer a whole day. Really, really need you guy's help. Any suggestion is highly appreciated, thank you.
