Homework Statement
A particle of mass m is attached to one end of a light elastic string of natural length a and modulus mg, the other end of the sting is attached to a fixed point O on smooth horizontal surface. The particle is released from rest at horizontal distance a+L from O.
calculate the force due to extension of string.
Homework Equations
The Attempt at a Solution
obviously one of the force will be 'mg' but force due to extension is hard to calculate. the answer for that one is mgx/a.
Also I am not sure if that modulus means young modulus
PLEASE help me
