Wonder woman is attempting to launch the joker into deep space, where he will never be able to hurt anyone again. the probe and the joker have a total mass of 450 kg, and the rocket has an exhaust velocity of 4250 m/s. a) how fast does the rocket need to go to reach escape velocity? (hint: earth has a mass of $5.972 * 10^{24}$ kg and a radius of $6.38 * 10^6$ m). b) find the mass of fuel needed for the rocket. c) find the mass expulsion rate of the rocket so that we can be rid of the joker forever.
