A spring is compressed between two toy carts of mass ${\mathrm{m}}_1$ and ${\mathrm{m}}_2$. When the toy carts are released, the springs exert equal and opposite average forces for the same time on each toy cart. If $v_1$ and ${\mathrm{v}}_2$ are the velocities of the toy carts and there is no friction between the toy carts and the ground, then :
