Hi, A space probe is launched from the equator in the direction of the north pole of the Earth. During launch the energy given to the probe of mass m is E=(3GMm/RE) Deduce that the Space probe will not be able to travel into deep space. That is a past paper question my teacher gave me. I am very confused because I was confident it would be able to escape due to the fact the energy is three time that required: GMm/RE Anyone has any explanations or is the question just wrong? Thanks!
