You pull the mass down by 10cm and release it so that it begins to oscillate. Calculate the work applied to the spring. The coefficient of friction of the spring is 28.22. If more data is needed then i will try and provide what little i have.

Hi there,
I'd like to help you with this problem, but I need to know what the spring constant is. When you say the coeffcient of friction of the spring is 28.22, do you mean the spring constant is 28.22 N/m? That would make more sense, but I'd rather ask then assume what you mean by that statement.

Many Smiles,
Craig
