Question

Epe=K.X²/2 Epe=50.(0.08)²/2 Epe=

Answer 1

Resposta:

Constante elástica = 50 N/m

Deformação = 0,08 m

Energia Potencial Elástica = ?

$\sf E_{pe}=\dfrac{k\cdot x^2}{2}$

$\sf E_{pe}=\dfrac{50\cdot (0,08)^2}{2}$

$\sf E_{pe}=\dfrac{50\cdot 0,0064}{2}$

$\sf E_{pe}=50\cdot 0,0032$

$\red{\sf E_{pe}=0,16~J}$
