You land on an alien planet. While in orbit, you see that the radius is 4075 km. While on the surface, you drop a rock (from rest) from a height of 1.50 m above the surface and you observe that the rock takes 0.734 s to reach the ground.

What is the mass of the planet?

What is the average density of this planet? (Assume the planet is spherical. The volume of a sphere is  V = 4 3 π r 3)

What do you name this new planet?

In order to measure the mass of an alien planet, imagine you put a spacecraft moving in a circular orbit of radius 400000 km around this planet. You happen to be located in the plane of the spacecraft's orbit. You find that the spacecraft's radio signal varies periodically in wavelength between 4.99979 mm and 5.00021 mm . Assuming that the radio is broadcasting normally, at a constant wavelength, what is the mass of the planet?

The small spherical planet called "Glob" has a mass of 7.56×1018 kg and a radius of 6.44×104 m. An astronaut on the surface of Glob throws a rock straight up. The rock reaches a maximum height of 1.36×103 m, above the surface of the planet, before it falls back down. What was the initial speed of the rock as it left the astronaut's hand? (Glob has no atmosphere, so no energy is lost to air friction. G = 6.67×10-11 Nm2/kg2.)...

Imagine you crash land your spacecraft on an unknown planet. The planet looks similar to earth, but you are not sure. To give you a hint on whether you are on earth or not, you drop a ball of mass 76.5 g from the top your spaceship. The height of the spaceship is 60 ft. The ball takes 2.5 s to reach the ground. Determine if you are on earth. If your weight on earth is 180 lbf, what is...

As an astronaut, you observe a small planet to be spherical. After landing on the planet, you set off, walking always straight ahead, and find yourself returning to your spacecraft from the opposite side after completing a lap of 25.2 km. You hold a hammer and a falcon feather at a height of 1.49 m, release them, and observe that they fall together to the surface in 28.8 s. Determine the mass of the planet.

Upon landing on an alien planet which lacks an atmosphere, you perform an experiment designed to determine the acceleration due to gravity. A small but powerful cannon fires a ball directly upwards from ground level with the ball leaving the cannon with a speed of 37.5 m/s. The ball is measured to reach a maximum height of 311.0 m. (11.1) What is the acceleration due to gravity on this planet ? (11.2) How much time elapses between the ball leaving...
