Given the following data for the planet mars: polar radius 3,389.5 km mass = 6.4171 x 1023 kg g-6.67408 x 101 m/kg s and that the universal gravitational constant is neglecting friction in the thin martian atmosphere, calculate the escape speed for a 10,000 kg spacecraft blasting off from the martian north pole. remember, the escape speed calculation assumes that t spacecraft uses all of its fuel in an initial "blast" and then coasts the rest of the way to "infinity."
