Please answer number 3, if it helps I know the answer is supposed to be m = 5.15 x 10^23 kg 3. An astronaut is standing on an unknown planet. If he estimates the planet is 2.505 x 10°m inradius and he can drop a ball of mass 0.250kg and it falls from a height of 8.00m in 1.71s, what isthe mass of the planet?4. A space station is being designed so that its outer ring rotates to give the illusion of gravity tothose standing inside of it. If the ring is 200.m in diameter, what will its period need to be in orderto simulate Earth's gravity? What will the linear velocity and angular velocity of an object withinthe ring be?5. The Earth's moon (m = 7.348 x 1022 kg; orbit = 3.84 x 10 m) has a linear velocity of 1022 m/s.This is not the expected linear velocity of the moon! What is the expected value, and what doesthis portend for the future of the moon?

In 1999, NASA lost the Mars Climate Orbiter because one group of engineers used metric units in their calculations while another group used English units. Consequently, the orbiter descended too far into the Martian atmosphere and burned up. Suppose that the orbiter was to have established orbit at 157 km and that one group of engineers specified this distance as 1.57 x 10³ m. Suppose further that a second group of engineers programmed the orbiter to go to 1.57 x 10³ ft. The $125 million Mars Climate Orbiter was lost in the Martian atmosphere in 1999 because two groups of engineers failed to communicate with each other about What was the difference in kilometers between the two altitudes?

Newton's universal law of gravitation can be stated as the force F of gravitation between two objects varies jointly as the masses m, and m, of the objects, and Gm,m2 inversely as the square of the distance r between their centers, where G is the constant of proportionality. In other words, F = The weight of an object is the force F on the object due to gravity, where F = mg. State how g (the acceleration due to gravity) varies with respect to the mass m, of the spherical body on which the object lies, and the radius of that body (assume all of the mass is at its center.). The acceleration due to gravity, g, varies as the spherical body's mass, and as
