# If a worker pulls a 10kg bucket up a 25 m well, how much work has he or she done?

$2450$ joules
Work done $W$, when an object of mass $m$ $k g$ is raised to a height of $h$ $m$ is given by $W = m g h$ joules, where $g$ is acceleration due to gravity in $S I$ units and is $9.8$ $\frac{m}{s} ^ 2$.
$10 \times 9.8 \times 25 = 2450$ joules
