Is this equation any good for finding a

x=1/2 at^{2+}v_{0}t +x_{0}

Given that v_{0}t=0 and x_{0}=0

I am trying to find the acceleration give that I dropped an eye dropper at 20cm and the average time was 0.116sec

2. Relevant equations

I have isolated it to a, where it is A= 2x over t^{2}

3. The attempt at a solution

I have calculated it to be 2972cm/s^{2}, then i divided it by 100 to get 29.72m/s^{2}. Isnt the standard 9.8m/s^{2}. I have also timed other objects and it seems they are all different.
