Spring and constant friction force

This following applet is Spring and constant friction force
Created by prof Hwang Modified by Ahmed
Original project Spring and constant friction force

A spring with original length L0 with a block at one end (another end is fixed).
You can use mouse to drag the block to change it position.
The spring will try to move back to it's equilibrium position.
Spring force F= -k *(L-L0)

There is a friction force between block and the floor, Fr= -mu*m*g;

There are three curves show x(t), vx(t) and K(t)=(1/2)m vx2(t).
Another spring will be drawn when you click show L0 , you can drag it to change the original length L0.
