3 Eris is the ninth most massive body orbiting the Sun It is more massive than Pluto and three times farther away from the Sun Eris is estimated to have a radius of approximately 1200 km Explore the force of gravity on the surface of Eris by solving the following three parts a Suppose that an astronaut stands on Eris and drops a rock from a height of 0 30 m The rock takes 0 87 s to reach the surface Calculate the value of g on Eris b Calculate the mass of Eris c Suppose that an astronaut stands on Eris and drops a rock from a height of 2 50 m calculate how long it would take the rock to reach the surface
