Two rigid steel spheres approach each other, with one sphere moving to the right and the other to the left. There are no external, unbalanced forces acting on either sphere before the collision or after the collision. The spheres collide and bounce off each other. How does the motion of the center of mass of the two sphere system change as a result of the collision

Which graph shows the greater change in momentum?

Use the figure below to answer question 11

A block of mass \(2m\) is placed in front of a spring of spring constant \(k\). The spring is compressed a distance \(L\) from its natural length and released. At the instant the block spring reaches its natural length, the block of mass \(2m\) collides with a second, smaller block of mass \(m\), and the two blocks stick together. Determine the speed of the block of mass \(m\) in terms of \(k\), \(L\), and \(m\) after the collision.
