An astronaut standing on a new planet wants to find the mass of the planet. His friend in the orbiting space shuttle tells him the radius of the planet is 2500 m. When he drops a rock from a height of 1.8 meters it takes 2.1 seconds to hit the ground. What is the mass of the planet?

An astronaut standing on a new planet wants to find the mass of the planet. His friend in the orbiting space shuttle tells him the radius of the planet is 2900 m. When he drops a rock from the height of 1.5 m it takes 2.9 seconds to hit the ground. What is the mass of the planet. I keep getting 4.5 *10^22 and idk why it is wrong.

An astronaut that got stranded on a planet with unknown characteristics is at the top of a cliff. He does not know the acceleration of gravity on that planet, but owns a clock to make measurements. He wants to know the height of the mountain he's standing on, so he made two measurements. First, he drops a rock from the border of the cliff and finds that it takes 2 seconds to touch the ground. Then, he throws the another...
7. An astronaut shipwrecked on a distant planet with unknown characteristics is on top of a cliff, which he wishes to descend He does not know the acceleration due to gravity on the planet. and he has only a good watch with which to make measurements. He wants to learn the height of the cliff, and to do this, he makes two measurements (Fig. 2-2 ). First, he lets a rock fall from rest off the cliff edge; he finds...
An astronaut with a mass of 70 kg is standing on the surface of a spherical asteroid that is 10 km in diameter and has a mass of 1x1015 kg. He knows he can jump straight up 0.2 meters on Earth with his spacesuit on. Can he generate enough energy by jumping to propel himself high enough off of the surface of the asteroid to grab a spacecraft that is orbiting 1 km above? (G=6.67x10-11Nm2/kg2 , g=9.8m/s2)

Mm 9x Weight of an object on the X-planet surface Weight W = F = mgx G = 6.67 x 10-11 Gravitational acceleration on a X-planet EX-8 In a 2014 epic science fiction movie, Interstellar, a small group of astronauts travel through a wormhole near Saturn in search of a new home for humanity. In the film the astronauts are even able to close a black hole (mass is very large) called Gargantua. Now assume these astronauts are landed at...
Prob 1 An astronaut lands on planet Suffrin of known radius R. She throws a rock to a height H directly above her hand (H < R), and she catches it after T seconds. (a) Find the acceleration due to gravity on the surface of Suffrin, in terms of H and T. Ans: (b) Find Suffrin's mass, Ms, in terms of H, T, R and the gravitational constant, G.
Consider an airless, non-rotating planet of mass M and radius R. An electromagnetic launcher standing on the surface of this planet shoots a projectile with initial velocity v0 directed straight up. Unfortunately, due to some error, v0 is less than the planet’s escape velocity ve; specifically, v0 = 0.701 ve. Unable to escape the planet’s gravitational pull, the projectile rises to a maximal height h above the ground, then falls back to the ground. Calculate the ratio h R of...
6. An astronaut ona distant planet wants to determine its acceleration due to gravity. The astronaut throws a rock straight up with a velocity of +15 m/s and measures a time of 20.0 s before the rock returns to his hand. What is the acceleration (magnitude and direction) due to gravity on this planet? See Diagram below: 20.0s v,15 m/s Show your work below: 7.
