A light horizontal spring has a spring constant of 105 N/m. A 2.00 kg block is pressed against one end of the spring, compressing the spring 0.100 m.
After the block is released, the block moves 0.250 m to the right before coming to a rest.
What is the coefficient of kinetic friction between the horizontal surface and the block?
The answer is 0.107 (back of the book... XD), but I don't know HOW to get it... and that's what's important... .___.
Help please
