What is the spring constant for the spring?

Click For Summary
SUMMARY

The spring constant for a spring with a mass of 2.74 kg oscillating at a frequency of 1.972 Hz is calculated using the formula f = 1/2π√(k/m). The correct calculation yields a spring constant k of approximately 4.3184 N/m. However, the initial poster indicates that this answer is incorrect, prompting a request for clarification and a more careful reevaluation of the calculation process.

PREREQUISITES
  • Understanding of harmonic motion and oscillation principles
  • Familiarity with the formula for frequency in relation to mass and spring constant
  • Basic algebra skills for rearranging equations
  • Knowledge of units of measurement, specifically Newtons per meter (N/m)
NEXT STEPS
  • Review the derivation of the formula f = 1/2π√(k/m)
  • Practice calculating spring constants with different masses and frequencies
  • Explore the concept of oscillation frequency in various physical systems
  • Investigate the effects of damping on oscillatory motion
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and oscillatory motion, as well as educators seeking to clarify concepts related to spring constants and harmonic oscillators.

Homework Statement


A mass 2.74 kg is hung from a spring. The mass is pulled down a short distance and released, it oscillates with a frequency f = 1.972 Hz.

What is the spring constant for the spring?

Homework Equations


f=1/2pi*sqrt(k/m)

The Attempt at a Solution


1.972 = 1/2pi*sqrt(k/2.74)
Rearranged:
k = (1.972/ 1/2pi)^2 x 2.74
= 4.3184 N/m

But this answer is wrong? Can someone please show me how this is so? Thank you

Redo your calculation a bit more carefully.
