You were right. I was calculating the acceleration properly, but I wasn't updating the position right. I've updated the code (show above) and now it works like a charm. Thanks Jacob! You were right.

Take a look at equation 5 on the Wiki page you linked. Try something like this.currentPos += this.speed - 0.5 * this.acceleration; When calculating the new position you need to take the acceleration into account, as it is not constant over the small distance you’re moving the object.
