Your spaceship lands on an unknown planet. To determine the characteristics of this planet, you drop a wrench from 4.50 m above the ground and measure that it hits the ground 0.814 s later. Part A) What is the acceleration of gravity near the surface of this planet? Express your answer with the appropriate units. Part B) Assuming that the planet has the same density as that of the earth (5500 kg/m3), what is the radius of the planet? Express your answer with the appropriate units.
