Dear experts,

This is regarding the Spring forces.

A Spring with spring constant 'k' is grounded on the lower end. A weight of 'm1' grams is hanged down from its upper end towards down using a thread length L.

(Q1) Here I would like to know the formula to calculate force acting down toward, due to the hanging weigh.

And at this moment a freely falling body of mass 'm2' is falling on the spring from height H with the help of guiders (to make sure it falls ont the spring).

(Q2) Here I would like to know the formula to calculate the corce acting on the mass 'm2' which will be oppsite to gravity

I am a non mechinical guys, for give me incase of any mistakes :)

Thanks in advance!

Electron

Hi PtrElectron! Welcome to PF! :smile:

Start by telling us what formulas you know about springs (including energy).

(on this forum, you have to do the work! :wink:)
