. You read in the newspaper that rocks from Mars have been foundon Earth. Your friend says that
the rocks were shot off Mars by the large volcanoes there. Youare skeptical so you decide to
calculate the magnitude of the velocity that volcanoes ejectrocks from geological evidence. You
know the gravitational acceleration of objects falling near thesurface of Mars is only 40% that on
the Earth. You can look up the height of Martian volcanoes anddetermine the distance rocks from
a volcano hit the ground from pictures of the Martian surface.If you assume the rocks farthest
from a volcano were ejected at an angle of 45 degrees, what isthe magnitude of the rock's
velocity as a function of its distance from the volcano and theheight of the volcano for the rock
furthest from the volcano?
