From a distance‑time graph of a car the following data points are recorded: (0 s, 0 m), (2 s, 12 m), (5 s, 30 m) and (7 s, 38 m). (a) Assuming the segment between 2 s and 5 s is linear, determine the instantaneous speed of the car on that interval. (b) If each distance reading has an uncertainty of \(\pm0.2\) m and each time reading an uncertainty of \(\pm0.1\) s, calculate the absolute uncertainty in the speed obtained in part (a). Give your final answer as speed \(\pm\) uncertainty in \(\text{m s}^{-1}\).

A. 6.2 ± 0.3 m s^{-1}

Correct Answer B. 6.0 ± 0.3 m s^{-1}

C. 5.5 ± 0.3 m s^{-1}

D. 6.0 ± 0.2 m s^{-1}

Correct Answer

Correct Option:

6.0 ± 0.3 m s^{-1}
