To escape from the solar system, how fast did the Pioneer 10 have to be travelling as it passed the orbit of Jupiter? Assume the mass of the solar system is essentially concentration in the Sun. The mass of the Sun is 1.99 x 10^30 kg and the radius of Jupiter's orbit is 7.78 x 10^11 m.

I am confused as to what quantities are relevant in this situation. I know that Jupiter must be used to carry out with escape velocity, but I don't have the mass of it.
