Uncertainty of Coefficient

Uncertainty of Coefficient#

The drag force on an object of interest can be accurately modelled as $\vec{D}$ = - $b \vec{v}$ such that its terminal velocity in free fall is given by $v_{T}$ = $m g / b$ . Emilia measures $m$ = 86 $\pm$ 2 $g$ and $v_{T}$ = 2.4 $\pm$ 0.2 $m / s$ . Based on these measurements Emilia determines the drag coefficient to be $b$ = 0.69 $k g / s$ .

Part 1#

What is the uncertainty in your determination of $b$ ?

Answer Section#

$\pm$ 0.11 $k g / s$
$\pm$ 0.07 $k g / s$
$\pm$ 0.01 $k g / s$
$\pm$ 0.74 $k g / s$
