Question

A 20 cm long spring is attached to a wall. the spring stretches to a length of 22 cm when you pull on it with a force of 100 n. what is the spring constant, "k" of the spring?

Answer 1

This phenomenon can be describedby Hooke'slaw and expressed by the formula: F=k*deltax, where k is the spring's constant, and delta xis the displacement of the spring. Transposing the terms such that we want to know the value of k,

k = F/deltax = 100N/(22 cm - 20cm)
k = 50 N/cm
