Final answer:
In the humorous scenario presented, the work done by the fart as it slows down to 0 m/s is zero since it involves internal forces and there is no external force doing work on the fart particles according to classical physics principles.
Step-by-step explanation:
The question provided involves concepts of physics related to mechanics, specifically it deals with the principle of conservation of energy and work done by a force. While the question about a fart in space is framed humorously, the same principles of physics apply as with any object in motion. To find the work done, one typically uses the work-energy theorem, which states that work done by the forces on an object equals the change in kinetic energy of the object.
However, in the given scenario, if we consider the fart particles as the system, there is a deceleration, and the final velocity becomes 0 m/s after 19 seconds. Since the particles are slowing down without any mention of an external force doing work, we would assume that this deceleration is due to internal forces within the system (like friction or resistance), which do not contribute to work in the classical physics sense. Therefore, according to the context given, the work done by the fart as it slows down is effectively zero, as no external force is applied, and internal forces do not count towards work done on the system.
