Acceleration of mass on a spring

Click For Summary

Homework Help Overview

The problem involves a mass placed on a vertical spring, which compresses to a new equilibrium position. The mass is then further compressed by a distance, and the question seeks to determine the acceleration of the mass after the spring is released. The subject area pertains to mechanics, specifically involving springs and forces.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster expresses uncertainty about how to begin the problem and identifies the equation F = -kx as relevant but notes the absence of a spring constant. Other participants suggest that the lack of a numerical value for the spring constant does not prevent progress, indicating that the answer can be expressed in terms of k. There is discussion about deriving the spring constant from the mass and displacement.

Discussion Status

The discussion is ongoing, with participants exploring different interpretations of the problem. Some guidance has been provided regarding the relationship between the spring constant and the mass, but no consensus has been reached on a specific approach or method to solve the problem.

Contextual Notes

Participants are working under the constraint of not having a specific value for the spring constant, which influences their reasoning and approach to the problem.

Homework Statement


A 2.0 kg mass is placed on top of a vertical spring, which compresses to a new equilibrium position; the spring is then compressed from this new equilibrium position by a distance of 0.05 m. What will be the acceleration of the mass just after the spring is released from this position?

I don't really know where to start. The only equation I can find that is relevant is F= -kx. But no spring constant is given. Any help please?

All I'm really asking for here is the starting point. I think I can do it from there, I just don't know where to get started from.
 
It doesn't matter if they don't give you a numerical value for k. It means your answer will depends of k.
 
So what do I do then. Consider that k=mg/x? then from there I can find the force. Then set that value to F=ma?
