$57 N$ $57N$

Explanation:

$Mechanical Advantage = \frac{output force}{input force}$ $"Mechanical Advantage" = "output force"/"input force"$
Here, Output Force is the weight of the bucket, $285 N$ $285N$ , and Input Force is the force needed to lift it.

$\Rightarrow Input Force$ $=> "Input Force"$ $=$ $=$ $\frac{output force}{mechanical advantage}$ $"output force"/"mechanical advantage"$
$= \frac{285}{5}$ $=285/5$
$= 57 N$ $=57 N$
