Experimental setup procedure taken to introduce external disturbances on the system. The figures are snapshots of three different moments that show (from the left to the right): the initial height of the 5 kg at the release phase; the weight in free fall; and the weight height in steady state. The rope length allows for a free fall of about 50 cm, leading to an impact velocity about 3.13 m/s and weight momentum about 15.66 kgm/s.
