$m \approx 3.878$ $m~~ 3.878$ Kg

By Newton's second law,
$F = m a$ $F=ma$
Where, $F$ $F$ = Force
$m$ $m$ = mass of object
$a$ $a$ = acceleration of the object

We write it also as,
$W = m g$ $W=mg$
Where, $W$ $W$ =weight
$m$ $m$ = mass of object
$g$ $g$ = acceleration due to gravity.

So, $W = m g$ $W=mg$
$m = \frac{W}{g}$ $m= W/g$

$m = \frac{32}{8.25}$ $m= 32/8.25$ Kg

$m \approx 3.878$ $m~~ 3.878$ Kg

An object weighs 3232 NN. What is its mass if a gravitometer indicates that g=8.25g = 8.25 mm/sec2/sec^2?
