Question

A force of 75 n is applied to a spring, causing it to stretch 0.3 m. what is the spring constant of the spring?

Answer 1

250 N/m

According to "e2020", this is correct

Answer 2

Answer: The spring constant of the spring is -250 Newton/ meter.

Step-by-step explanation:

Force exerted on the spring = 75 Newton

Distance up-to spring stretched = 0.3 meter

`F=-kx`

Negative sign means that force is in opposite direction.

`75 Newton=-k(0.3 meter)`

`k=-250 Newton/ meter`

The spring constant of the spring is -250 Newton/ meter.
