A heavy ball with an initial kinetic energy of 4000 J is trapped inside a box with rigid walls containing a cylinder constructed of small light-weight spheres. The ball crashes into the cylinder and breaks it apart. The bar graph at the right, as well as the table at the bottom, displays the kinetic energy of the ball. Do you think it is possible to recollect all the energy from the spheres and transfer it back into the red ball without an external interaction? Note: Simulation will run for about 20 seconds. Start
