The radius of Mars (From the center to just above the atmosphere) is $3.40\times 10^6\mathrm{m}$, and its mass is $6.00\times 10^{23}\mathrm{kg}$. An object is launched straight up from just above the atmosphere of Mars. What initial speed is needed so that when the object is far from Mars its final speed is $1960\mathrm{m}/\mathrm{s}$ ? $v=$ Tries 6/8 Previous Tries What initial speed is needed so that when the object is far from Mars its final speed speed is $0\mathrm{m}/\mathrm{s}$ ? (This is called the "escape speed.") Previous Tries
