You have been visiting a distant planet. Your measurements
have
determined that the planet's mass is twice that of the earth but
the
free fall acceleration at the surface of the planet is only one
fourth
of that at the surface of the earth.
a) What is the planet's radius
b) To get back to earth you need to escape the planet. What
minimum
speed does your rocket need?

A new planet has been discovered that has a mass one-ninth that of Earth and a radius that is eight times that of Earth. Determine the free fall acceleration on the surface of this planet. Express your answer in the appropriate mks units. A new planet is discovered orbiting a distant star. Observations have confirmed that the planet has a circular orbit with a radius of 10 AU and takes 198 days to orbit the star. Determine the mass of...

A new Earth size planet has been discovered in a distant star system. The planet has six times the mass of Earth and has a radius of twice the radius of the Earth. Do NOT mix or change system of units! There is an equation in the posted handout for solving this problem. If you do not use it you will only receive 1 point for this problem no matter your answer. What is the acceleration due to gravity on...

The mysterious visitor that appears in the enchanting story The Little Prince was said to come from a planet that “was scarcely any larger than a house!” Assume that the mass per unit volume of the planet is about that of Earth and that the planet does not appreciably spin. Take the diameter of the planet to be 14 m. Approximate (a) the free-fall acceleration on the planet's surface and (b) the escape speed from the planet.

You are exploring a distant planet. When your spaceship is in a circular orbit at a distance of 630 km above the planet's surface, the ship's orbital speed is 5200 m/s. By observing the planet, you determine its radius to be 4.48×106m. You then land on the surface and, at a place where the ground is level, launch a small projectile with initial speed 11.6 m/s at an angle of 30.8∘ above the horizontal. a)If resistance due to the planet's...

You are the science officer on a visit to a distant solar system. Prior to landing on a planet you measure its diameter to be 1.60×107 m and its rotation period to be 22.3 hours. You have previously determined that the planet orbits 2.10×1011 m from its star with a period of 402 earth days. Once on the surface you find that the free-fall acceleration is 12.2 m/s2 . Part A: What is the mass of the planet? Part B:...

3. Captain Janeway is preparing to leave a planet with a mass of 4.50 x 1025 kg and a radius of 12,500 km in a shuttle craft of mass 8 250 kg. (a) What is the acceleration due to gravity on the surface of this planet? (b) What must her speed be if she is to enter a circular orbit 512 km above the surface of the planet? (c) How much work must the thrusters of Janeway's shuttle do in...

You are the science officer on a visit to a distant solar system. Prior to landing on a planet you measure its diameter to be 1.8 x 10' m and its rotation period to be 22.3 hours. You have previously determined that the planet orbits 2.2 x 1011 m from its star with a period of 417 earth days. Once on the surface you find that the free-fall acceleration is 12.2 m/s.
