 # Example 3.2. Particle in a pinned tube  
 
 Figure 3.14 depicts a particle of mass $m$ connected to inertial point A by means of a spring of stiffness $k$ and dashpot of constant $c$ . At the initial time, the particle is located at $\theta\:=\:0$ , $\phi\,=\,\pi/2$ , and $r~=~r_{0}$ , which corresponds to the un-stretched configuration of the spring; $r$ , $\phi$ , and $\theta$ form a spherical coordinate system, see section 2.7.2. The initial velocity vector of the particle is $\underline{{v}}_{0}$ . Derive the equations of motion of the system.
