In an experiment to determine the acceleration of free fall g, the time t taken for a ball to fall through distance s is measured. The percentage uncertainty in the measurement of s is 2%. The percentage uncertainty in the measurement of t is 3%.
The value of g is determined using the equation shown.
$g = \frac{{2s}}{{{t^2}}}$
What is the percentage uncertainty in the calculated value of g?
