A balanced lever has two weights on it, the first with mass $72 k g$ $72 kg$ and the second with mass $9 k g$ $9 kg$ . If the first weight is $2 m$ $2 m$ from the fulcrum, how far is the second weight from the fulcrum?

$y = 16 m$ $y=16 m$

Explanation:

$F_{1} : the first weight$ $F_1:" the first weight"$
$F_{2} : the second weight$ $F_2:" the second weight"$
$x : distance between F_{1} and fulcrum$ $x:" distance between " F_1 " and fulcrum"$
$y : distance between F_{2} and fulcrum$ $y:" distance between " F_2 " and fulcrum"$
$F_{1} \cdot x = F_{2} \cdot y$ $F_1*x=F_2*y$
$cancel(72)*2=cancel(9)*y$
$8*2=y$
$y=16 m$
