+394 The expanding spring continues to impart energy to the ball as long as there is contact. At separation, it no longer accelerates so that is the maximum velocity. After this point, the ball begins to decelerate, until it reaches the peak, where it stops, and the ball begins to accelerate in the opposite direction.
If this were a closed system, where the energy was not lost to friction, this ball would “bounce” indefinitely. It is the same reason why planets orbit a sun for billions of years. This kind of system has miniscule friction and gravitational perturbations.
