Question 1

A student investigates the stretching of a spring in a physics laboratory.

The spring constant (kkk) of the spring is 25 N/m.

The spring is stretched so that its extension is 0.080 m.

Calculate the force applied to stretch the spring.

Use the equation:

force=spring constant×extension \text{force} = \text{spring constant} \times \text{extension} force=spring constant×extension
