Your spaceship lands on an unknown planet. To determine the characteristics of this planet, you drop a wrench from 3.00 m above the ground and measure that it hits the ground 0.814 s later. a) What is the acceleration of gravity near the surface of this planet? b) Assuming that the planet has the same density as that of earth (5500 kg/m^3), what is the radius of the planet?
