Consider a spinning space station, the normal force exerted by the wall keeps the astronauts in circular motion. They feel the normal force like the gravity on Earth. If we want a space station spinning at one revolution per minute to have an apparent gravity equal to that on Earth, what should be the radius of the station? Is that a reasonable size? Explain your opinion.

Read the resource about the International Space Station (ISS) located within the weekly readings. The space station orbits Earth about 400 km above the surface of Earth (NASA.gov). At this height the force of gravity from Earth is only about 10% less than on the surface of Earth. Using the concepts of circular motion and gravitational forces learned in this Topic; explain the following in your own words: Why does the space station not fall down? Why do the astronauts...

Different situation now. You re out in space, on a rotating wheel-shaped space station of radius 571 m. You feel planted firmly on the floor , due to artificial gravity. The gravity you experience is Earth-normal, that is, g = 9.81 m/s^2. How fast is the space station rotating in order to produce this much artificial gravity? Express your answer in revolutions per minute (rpm).

A circular space station (shaped like a big wheel) rotates 110 times in one hour. The apparent weight of an astronaut standing on the inside surface of the outer wall is equal to her weight on earth. How far from the axis of rotation is the inside surface of the station’s outer wall? Give the numerical value in meters.

There exists a circular space station with radius 1km where the gravitational pull of the sun and earth cancel. The rotation of the station is in a way that an eart like gravity exists in the ring, which can be considered as a hoop with 1km radius. 1. Find the required constant angular velocity of the station to accomplish this? 2. An astronaut approaches the station with his cylinder craft (radius = 25m, mass=250 kg, length = 300 m), and...

1. Dynamics and artificial gravity. The space station has two thrusters pointed in opposite directions. They operate by expelling propellant at high speed. The effect is that there is a force of magnitude F0 on the two ends of the space station in opposite directions, which causes the entire object to start rotating. The thrusters will stop firing when the artificial gravity created on the space station (described below) reaches the required value. Upward force, magnitude F0 Downward force, magnitude...

9. A NASCAR racecar rounds one end of the Martinsville Speedway. This end of the track is a turn with radius approximately 57.0 m. If we approximate the track to be completely flat and the racecar is traveling at a constant 26.5 m / s (about 59 mph) around the turn, what is the racecar\'s centripetal (radial) acceleration? ? m/s^2 What is the force responsible for the centripetal acceleration in this case? a) weight b) normal c) gravity d) friction...
