# How much work would it take to push a  3 kg  weight up a  11 m  plane that is at an incline of  pi / 6 ?

${E}_{p} = W = 161 , 87 J$

#### Explanation:

$\text{the given data}$
$l = 11 m$
$\theta = \frac{\pi}{6}$
$m = 3 k g$
$h = l \cdot \sin \theta$
$h = 11 \cdot 0 , 5 = 5 , 5 m$
${E}_{p} = W = m \cdot g \cdot h$
${E}_{p} = W = 3 \cdot 9 , 81 \cdot 5 , 5$
${E}_{p} = W = 161 , 87 J$
