How can i represent the following spring mass system

Question

How can i represent the following spring mass system?

[ spring mass system[1]

Welcome to TeX.SX! The short answer is that, yes, this is possible but I have to warn you that questions of the form "Please draw this for me" that show no effort on the part of OP, often don't get answered. You will get more help if you post some code showing what you have tried and give a minimal working example. A quick search on TeX.SX for drawing functions (with tikz or pstricks) will give you an idea of where to start from. — , Sep 20 '18 at 04:02
