Aspring stretches 0.220 m when a 0.400 kg-mass is hung from it. what is its spring constant? (mass is not a force ) (unit=n/m)

Spring constant is the measure of spring stiffness. The value of spring constant is 17.83 newton per meter.

Given information-

The length of spring stretches 0.220.

The mass of the object which hung on spring is 0.400 kg.

The spring constant has to find out.

Spring constant is the measure of spring stiffness.

Spring constant is the ratio of the force applied on the spring to the displacement of spring after the force has been applied. It can be given as,

Here the force acting on the body is weight of the body. The weight of the body is the product of mass and gravitational force . Hence,

As the value of the gravitational force is 9.81 meter per second squared. Put the values,

Hence the value of spring constant is 17.83 newton per meter.
