NASA scientists suggest using rotating cylindrical craft to recreate gravity while in a weightless environment. Consider such a craft that has a diameter of d = 124 m. What is the speed v, in meters per second, the craft must rotate at its outer edge to recreate the force of gravity on earth g. At what rate, in revolutions per minute, is the station rotating?

An astronaut orbiting the earth is preparing to dock with a Westar VI Satellite. The satellite is in a circular orbit 600 km above the Earth's surface, where the free-fall acceleration is 8.21 m/s2. Take the radius of the earth as 6400 km. Determine the speed of the satellite and the time interval it requires to complete one orbit around the Earth. which is the period of the satellite.

It is proposed that future space stations create an artificial gravity by rotating. Suppose a space station in constructed as a 1010.0 m diameter cylinder that rotates about its axis. The inside surface is the deck of the space station. What rotation period (in s) will provide "normal" gravitational acceleration of 9.80 m/s2 at deck level?

You are in a cylinder-shaped space station 120 m in diameter, rotated on its axis to provide 3 m / s2 "artificial gravity" to people walking around the inner wall of the outer rim. Explain by extracting data, diagrams and / or drawing of the problem, the proposed phenomenon. Find the rate of rotation of the cylinder (in revolutions per minute) that would provide this effect. You must raise the equations, make the correct substitution and write down your result with the appropriate units You are asked to achieve an artificial gravity of 9.81 m / s2, give a brief explanation of the implications that this entails.

A spacecraft orbits Mars at an average altitude of 405 km. The average radius of Mars is 3390 km. If it takes the spacecraft 1.95 hours to complete one orbit around the planet, what is it's tangential velocity in kilometers per hour?

A space exploration program proposes to make artificial gravity on a space station that looks like a circular ring with a 500 m diameter by having the space station rotate. At what angular frequency would the space station have to rotate so that someone standing on a scale in the outer ring of the space station would have an apparent weight the same as they would on Earth?

Engineers and science fiction writers have proposed designing space stations in the shape of a rotating wheel or ring, which would allow astronauts to experience a sort of artificial gravity when walking along the inner wall of the station's outer rim. 2 (a) Imagine one such station with a diameter of 123 m, where the apparent gravity is 2.20 m/s at the outer rim. How fast is the station rotating in revolutions per minute? rev/min (b) What If? How fast would the space station have to rotate, in revolutions per minute, for the artificial gravity that is produced to equal that at the surface of the Earth, 9.80 m/s? rev/min

A synchronous satellite, which always remains above the same point on a planet's equator, is put in circular orbit around Jupiter so that scientists can study a surface feature. Jupiter rotates once every 9.84 h. Use the data of this table to find the altitude of the satellite.
