If the work done to stretch an ideal spring by 4.0 cm is 6.0j, what is the spring constant (force constant) of this spring?

Spring constant or the force constant, k = 7500 N/m.

Explanation:

Given that,

Energy stored in the spring, E = 6 J

Stretching in the spring, x = 4 cm = 0.04 m

To find,

The spring constant (force constant) of this spring.

Solution,

We know that the work done by the spring when it is stretched is given by :

k is the spring constant

k = 7500 N/m

So, the spring constant (force constant) of this spring is 7500 N/m.
