In a tonga, horse pulls a wagon. Which is the correct analysis of the situation?
An oscillator of mass $M$  is at rest in its equilibrium position in a potential $V\, = \,\frac{1}{2}\,k{(x - X)^2}.$ A particle of mass $m$  comes from right with speed $u$  and collides completely inelastically with $M$ and sticks to it . This process repeats every time the oscillator crosses its equilibrium position .The amplitude of oscillations after $13$  collisions is: $(M = 10,\, m = 5,\, u = 1,\, k = 1 ).$
