Calculating Spring Force Constant from a Dropped Ball

Click For Summary
SUMMARY

The discussion centers on calculating the spring force constant (k) using a dropped ball's parameters. An 86.3g ball dropped from 52.3cm compresses a spring by 4.9296cm, with gravitational acceleration set at 9.8m/s². The conservation of energy principle is applied to derive the spring constant in N/m. A similar scenario with a 135g ball dropped from 62cm is also mentioned, indicating the need for consistent methodology in both cases.

PREREQUISITES
  • Understanding of conservation of energy principles
  • Familiarity with Hooke's Law and spring constants
  • Basic knowledge of gravitational acceleration (9.8m/s²)
  • Ability to perform unit conversions and calculations in physics
NEXT STEPS
  • Calculate the spring constant k using the formula k = (2 * m * g) / x, where m is mass, g is gravitational acceleration, and x is maximum displacement.
  • Explore the impact of varying mass on spring compression and force constant.
  • Investigate energy conservation in different mechanical systems.
  • Learn about the applications of spring constants in real-world engineering scenarios.
USEFUL FOR

Physics students, mechanical engineers, and anyone interested in understanding the dynamics of spring systems and energy conservation principles.

A 86.3g ball is dropped from a height of 52.3cm above a spring of negligible mass. The ball compresses the spring to a maximum displacement of 4.9296 cm. The acceleration of gravity is 9.8m/s^2. Calculate the spring force constant k. answer in units of N/m.

Conservation of energy ofcourse. :)
Take the reference level as the level at which the spring is compressed to the maximum displacement. Do you think you can go from there?
 
i have a similar question, except with different values.

135 g for mass of ball

62 cm above spring

9.8 is same for gravity
