The elongation of a spring can be calculated using Hooke's Law, represented by the equation F = -kx, where F is the force applied, k is the spring constant (119 N/m), and x is the elongation. To find the force, one must use the weight of the wooden block, which is calculated by multiplying its mass (4.17 kg) by the acceleration due to gravity (approximately 9.81 m/s²). The density of the wooden block (695 kg/m³) is irrelevant to this calculation. Thus, the elongation can be determined by rearranging the equation to x = F/k.
PREREQUISITESStudents studying physics, particularly those focusing on mechanics and spring dynamics, as well as educators looking for clear examples of applying Hooke's Law in problem-solving scenarios.

How do I find the elongation of a spring when just given K=119 N/m, mass of the wooden block it is attached to=4.17kg and the densty of the wooden block = 695 kg/m^3.
Homework Equations
I do not know what equation to use.
The Attempt at a Solution
I have not been able to make an attempt because I do not know what equation to start off with.
dban33 said:Homework Equations
The equation I was trying to use was Fx=-kx
I do not think this is correct because my answer was wrong.
dban33 said:Well I am trying to find the elongation of the spring. So the correct equation is F=-kx?
Does that mean that I change it to solve for x?? x= F/-k
I do not kno how to find the force for the equation if I only have the mass and density of the wooden block the string is attached to. I am completely lost!
