On dealing with Universal Gravitation topic, I came across this question:
what is the min speed, relative to the sun, necessary for a spacecraft to escape the solar system if it starts at the Earth's orbit?
My working:
v=sqrt(2GM/R), where G=universal constant, R= distance between Earth and sun and m= mass of sun. Is that all?
The second part of it states that a spaceship achieved a max speed of 125000km/h on its way to photograph jupiter. Beyond what distance from the sun is this speed sufficient to escape the solar system?
for the second part, any hints? I am getting stuck. Do i need to know the order of the planets for the second part?
