[QUOTE="Chestermiller, post: 6838253, member: 345636"] To get a better idea how this all plays out in a "practical" case, I have used Eqns. 6 and 7 of post #39 to establish the details of what transpires for the specific case where the mass of the platform is 100 kg. Here are the results of the calculations: The collision between the left mass and the left bumper occurs at 3 seconds at x = -12 m. After this collision, the velocities of the masses and the platform are $$v_L=3.619\ m/s$$$$v_R=2.0\ m/s$$and $$v_P=-0.381\ m/s$$The total momentum of the two masses and the platform remains zero. The collision between the right mass and the right bumper occurs at 5.52 seconds at x = 11.04 m. After this collision, the velocities of the masses and the platform are $$v_L=3.619\ m/s$$$$v_R=-2.327\ m/s$$and $$v_P=0.0519\ m/s$$The total momentum of the two masses and the platform remains zero. The final collision between the two masses occurs at 7.86 seconds at x = 5.59 m. The center of the platform at this time is at x = -0.84 m [/QUOTE]
