-The [[183_notes:energy_cons|Energy Principle tells you that the energy of this system is conserved]]. Moreover, you know from the final state where  $r\rightarrow \infty$  and  $v\rightarrow 0$  that both the final potential and final kinetic energies are zero. Hence, the total energy of the system must be zero.

-This speed defines the minimum speed needed to leave the planet and never return under the gravitational interaction between the object and the planet. Notice that this speed doesn't depend on the mass of the launched object (so long as it is much less than the planet).
