A cylindrical habitat in space 8.75 km in di-ameter and 28.5 km long has been proposed(by G.K. O'Neill, 1974). Such a habitat wouldhave cities, land, and lakes on the inside sur-face and air and clouds in the center. Thiswould all be held in place by rotation of thecylinder about its long axis.At what angular velocity would the cylinderhave to rotate to imitate the Earth's gravita-tional field at the walls of the cylinder? Theacceleration of gravity is 9.8 m/s² . Give youranswer in rad/s.Answer in units of rad/s.

Consider a cylinder of diameter d is rotating with an angular velocity ω to imitate the same gravity…

The Moon exerts a torque on Earth's tidal bulge. Although the tides are raised in part by the Moon itself, friction between the bulge and Earth's oceans and atmosphere cause it to be in front of the Earth-Moon line in the sense of Moon's motion around Earth. Consequently , the Moon applies a torque that is acting in opposition to Earth's rotation, and that is also trying to change the direction of the axis in space. The result is ... Pick those that apply.

A Mars observing satellite is orbiting on a circular orbit at an altitude of 1000 km above Mars’s equator. Find satellite’s acceleration and velocity as seen from a deep space communications station located on Earth’s equator, when they are on a direct line of sight (see the Fig. below). Assume for simplicity that planetary orbits and their equatorial planes are all in the plane of ecliptic (that is all, motion is in a 2D plane). Earth radius is 6300 km, Mars radius 3400 km, Mars mass 6.4x1023 kg. Assume that all circular motions are counter clockwise (i.e., orbital motions of Earth and Mars, Earth spin, and satellite orbital motion).
Two newly discovered planets follow circular orbits around a star in a distant part of the galaxy. The orbital speeds of the planets are determined to be 44.6 km/s and 51.6 km/s. The slower planet's orbital period is 8.78 years. (a) What is the mass of the star? (b) What is the orbital period of the faster planet, in years?
an effective way to create artificial gravity is through the use of a rotating cylinder, as shown in the figure. Humans walk on the edge of the cylinder which is sufficiently large (diameter of 3435 meters) that its curvature is not readable noticeable to the inhabitants. Once the space station is rotating at the necessary speed to create an artificial gravity of 1g how many minutes would it take to make one revolution

Wonder Woman and Superman fly to an altitude of 1630 km,1630 km, carrying between them a chest full of jewels that they intend to put into orbit around Earth. They want to make this tempting treasure inaccessible to their evil enemies who are trying to gain possession of it, yet keep it available for themselves for future use when they retire and settle down. But perhaps the time to retire is now! They accidentally drop the chest, which leaves their weary hands at rest, and discover that they are no longer capable of catching it as it falls into the Pacific Ocean. At what speed ?fvf does the chest impact the surface of the water? Ignore air resistance (in reality, it would make large difference). The radius and mass of Earth are 6370 km6370 km and 5.98×1024 kg,5.98×1024 kg, respectively.

A satellite is in circular polar orbit around Earth at an altitude of 450 km – meaning it passes directly overhead of the North and South Poles. What is the magnitude and direction of the displacement vector when it is directly over the North Pole to when it is at 40° latitude? Earth’s radius is 6,370 km.
