Two Elastic String
I don't understand what they have done in the mark scheme where I have put a red box around the part that I don't understand. Please help. Thanks in advance.
they are using
Gain in Kinetic energy + gain in elastic potential energy = Loss in Gravitational potential energy.
note for each string.
The strings elongate right? Those strings contain elastic potential energy. For calculation purposes, read Young's modulus - Wikipedia, the free encyclopedia
Yes your told that it is released form rest so the initial velocity is zero.
