Mass Spring Oscillator Animated GUI

Description:
Three masses are attached to each other by four springs. The masses slide along a friction-less horizontal surface and model is developed to animate positions of the three masses, and four springs.
The mass of each spring is negligible and there is no damping in the system. The springs operate according to Hooke’s law: Force = k(elongation) where constants k1, k2, k3, k4 denote the Hooke’s constants. The first and last spring are attached to fixed walls.
