Respuesta :

  • We know the formula

[tex]\\ \rm\Rrightarrow x=\dfrac{2mg}{k}[/tex]

[tex]\\ \rm\Rrightarrow x=\dfrac{2(1.5)(9.8)}{1200}[/tex]

[tex]\\ \rm\Rrightarrow x=\dfrac{3(9.8)}{1200}[/tex]

[tex]\\ \rm\Rrightarrow x=\dfrac{9.8}{400}[/tex]

[tex]\\ \rm\Rrightarrow x=0.0245m[/tex]

2.45cm is distance
