Answer 1

$answer$

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

$length \: of \: the \: effort \: arm40cm$

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

$mechanical \: advantage$

$we \: know \: that$

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

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