Vedclass · Answer

(D) The total energy $E$ of a satellite-planet system is given by $E = K + U$,where $K$ is the kinetic energy and $U$ is the potential energy.If $E If $E = 0$,the satellite is at the threshold of escaping the gravitational field (it moves with escape velocity $v_e$).If $E > 0$,the kinetic energy is greater than the magnitude of the potential energy,meaning the satellite has excess energy.Therefore,the satellite will escape the gravitational field of the planet with a speed greater than the escape velocity.
