In the case of a damped pendulum, how would the dyanmics change as a fixed point varied from being a stable spiral, to a stable degenerate node, to a stable node?
I know that all the trajectories continue to lose altitude, and that the pendulum goes from whirling clockwise over the top, loses energy, settles to a small oscillation, and eventually comes to rest at the bottom, but wasn't sure if this general description changes based on the variation of fixed points.
A 15-gram rifle bullet moving at 200 m/s hits a 3 kg block suspended from a 1:5 m long rope. If the bullet remains lodged inside the block, what will be the maximum angle reached by the ballistic pendulum after the collision?
A mathematical pendulum of mass 1.0 kg and length 1.0 m is moved by an angle 60° from the vertical axis and then let go. How fast does the wight move at the moment the rope encloses an angle of 30° with the vertical axis?

A small balloon containing sand with a combined mass of 98.2gg is suspended with an ideal string of length 86.6cmcm, forming a simple pendulum. The pendulum is released from an angle of 41.4∘∘ with the vertical, and it collides with a block of mass 333gg located where the pendulum string becomes vertical.
