Answer 2

$answer$

$length \: of \: the \: lever \: 2m \: = \: 200cm$

$length \: of \: the \: effort \: arm \: 40cm$

$length \: of \: the \: load \: arm \: is \: 200cm - - 40cm \: = 160cm$

$mechanical \: advantage$

$we \: know \: that$

$mechanical \: advantage \: = \: \frac{length \: of \: the \: effort \: arm}{length \: of \: the \: load \: arm}$

$ma \: = \: \frac{40cm}{160cm} = 0.25$
