Someday in the future, an astronaut on Mars (where gMars = 3.71 m/s^2) might lean over the edge of 25.0-meter-tall spacecraft and throw a package straight downward with an initial downward speed of 8.00 m/s.
a. How much time will it take for the package to strike the ground?
b. What will be the package's speed when it strikes the ground?
