Question

Constanta de elasticitate a unui resort este de 200N/m. Daca de resort suspendam un corp de masa 300g calculati alungirea resortului

Answer 1

[tex]\tt Se~da:\\ \\ k=200\frac{N}{m}\\ \\ m=300g=0,3kg\\ \\ \triangle l=?m\\ \\ \\ Formule: \\ \\ F_{el}=k \times \triangle l \Rightarrow \triangle l=\frac{F_{el}}{k}\\ \\ G=F_{el}\Rightarrow m \times g=F_{el} \Rightarrow \triangle l=\frac{m \times g}{k}\\ \\ \\ Calcule: \\ \\ \triangle l=\frac{0,3 \times 10}{200}=0,015m[/tex]
