A student takes measurements to determine the constant acceleration of a model car moving from rest in a straight line. The measured values with their absolute uncertainties are shown.
The student uses the equation $S = \frac{1}{2}a{t^2}$ to calculate the acceleration of the car.
What is the acceleration and its absolute uncertainty?

1 )
$(0.11 ± 0.01) m s^{-2}$
2 )
$(0.11 ± 0.02) m s^{-2}$
3 )
$(0.15 ± 0.01) m s^{-2}$
$(0.15 ± 0.02) m s^{-2}$
