Consider a particle bouncing between two stationary walls. The collision of the particle with one wall is elastic and with the other one is given by the following rule: the velocity of the particle increases by one if t ∈ [2n, 2n + 1] and decreases by one if t ∈ [2n + 1, 2n + 2], where n is a natural number and t is the moment of time at which the collision… (More)
