Use Hooke's Law, which states that the distance a spring stretches (or compresses) from its natural, or equilibrium, length varies directly as the applied force on the spring. A force of 265 newtons stretches a spring 0.15 meter. (a) What force stretches the spring 0.4 meter

Answer:

706.68 N

Explanation:

By Hooke's law,

[tex]F = ke[/tex]

[tex]k=\dfrac{F}{e}[/tex]

Using the values in the question,

[tex]k=\dfrac{265\text{ N}}{0.15 \text{ m}}=1766.7\text{ N/m}[/tex]

When e = 0.4 m,

[tex]F = 1766.7\text{ N/m}\times0.4\text{ m}=706.68\text{ N}[/tex]
