To find the acceleration of free fall $g$, an experiment measured the time $t$ for a ball to drop a distance $s$. The estimated uncertainty in measuring $s$ is $2\%$. The estimated uncertainty in measuring $t$ is $3\%$. The value of $g$ is found from the relation $g = \frac{2s}{t^2}$. What is the uncertainty in the calculated value of $g$?
- A$1\%$
- B$5\%$
- C$8\%$
- D$11\%$
