We know that the displacement of the upper eyelid is positive. So, the displacement of the eyelid as it closes is +12 millimeters.
Now, let's see which other variables we can identify. Let's start with the initial velocity of the eyelid. Look back over the problem statement at the beginning of this problem, and use it to determine what the initial velocity of the eyelid was before it started closing. Complete the self-quiz below to find out.
