I have a problem to do, in which I need to determine the acceleration of an object and the uncertainty of the acceleration. The position vs. time equation is given by:

s(t) = 0.205t

^{2}+ 0.3001t

Therefore, after differentiation, I can state the the velocity vs. time equation is:

v(t) = 0.410t + 0.3001

And that the acceleration of my object is:

a(t) = 0.410

The acceleration is constant, and this is the number that I'm looking for. However, I don't know how to calculate the uncertainty of the acceleration.

I know that the uncertainty of the position for the s(t) equation is +/- 0.005, and that the uncertainty of the time is +/- 0.15. How do I determine the uncertainty of the acceleration?
