If an astronaut dropped a small rock near the surface of Pluto, how far (in m) would the rock fall in 1.1 s? (The mass of Pluto is 2.500×10-3 the mass of earth and the radius of Pluto is 0.18 of the earth's radius.)
M=mass of planet
r=radius of planet
Calculate g (by relative proportions)
on Pluto and use new value of g for the free fall equation.
