Your starship lands on a mysterious planet. as chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 12.0 m/s returns to the ground in 6.00 s; the circumference of the mysterious planetat the equator is 2 ×10okm; and there is no appreciable atmosphere. the starship commander asks for the following information: (a) what is the mass of this mysterious planet? (b) if the starship goes into a circular orbit 30,000 km above the surface of the planet, how many hours will it take the ship to complete one orbit?
