Question

a load of 45 N attached to a spring that is hanging vertically stretches the spring 0.14 m. What is the spring constant?

Answer 1

Answer:

Spring constant, k = 321.42 N/m

Explanation:

Force acting on spring, F = 45 N

Displacement caused due to stretching, x = 0.14 m

Using Hooke's law :

$F=-kx$

Where

k is the spring constant

$k=\dfrac{F}{x}$

$k=\dfrac{45\ N}{0.14\ m}$

k = 321.42 N/m

Hence, this is the required solution.

Answer 2

According to Hooke's law, Force = spring constant x displacement of the spring. Spring constant = Force/displacement in spring = 45/0.14 = 321.42 N/m. Hope this helps!
