1. Considere el muelle de la Figura 2 con k Æ 20,4N/m. Colgamos una masa de 500g del muelle y esperamos hasta que esta queda en reposo.
a) Teniendo en cuenta la ley de Hooke, ¿Cuál es el desplazamiento x
dado en el extremo del muelle?
b) ¿Cuál es el trabajo realizado al estirar el muelle?
c) Si añadimos otra masa de500g, el muelle se estirará otros0,240m,
hasta xB Æ 0,480m.. Calcular el trabajo adicional.
2. Un muelle que cumple la ley de Hookey con constante k Æ 135N/m se
comprime9,50cm a partir de la posición de equilibrio. ¿Cuál es el trabajo
requerido para realizar esta compresión?
3. Un muelle que cumple la ley de Hooke tiene una constante k Æ 500N/m.
¿Cuál es el trabajo realizado para estirar el muelle desde x Æ 0,30m a x Æ
0,40m?
4. Si13,4J de trabajo permiten comprimir un muelle 2,37cm,¿cuál será la
constante del muelle?
