F = 4 Newton – the force that acts on the spring;
k = 40 Newton / meter – spring stiffness.
It is required to determine dx (meter) – how much the spring will elongate under the influence of the force F.
According to Hooke’s law, we find the amount of elongation of the spring by the formula:
F = dx * k, from here we find:
dx = F / k = 4/40 = 1/10 = 0.1 meter (10 centimeters).
Answer: under the action of a force of 4 Newton, the spring will lengthen by an amount equal to 0.1 meter (10 centimeters).
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
