Your spaceship lands on an unknown planet. You drop a 1.50 kg wrench from 5.50 m above the ground and measure that it hits the ground 0.811 s later. You also do enough surveying to determine that the circumference of the planet is 6.00 x 10^4 km.
Part A: What is the mass of the planet, in kilograms?
Part B: Express the planet%u2019s mass in terms of the earth%u2019s mass.
