A proposed space station includes living quarters in a circular ring 50.0 m in diameter. At what angular speed should the ring r
mel-nik [20]
Given that the space station is free of gravitational force, it is required that it spins an certain speed to acquire centripetal acceleration.

In this case, you want that the centripetal acceleration, Ac, equals g (gravitational acceleration on the earth), becasue this will cause a centripetal force equal to the weight on earth.

The formula for centripetal acceleration is Ac = [angular velocity]^2*R

where R = [1/2]50.0m = 25.0 m

Ac = 9.81 m/s^2

=> [angular velocity]^2 = Ac/R = 9.81m/s^2v/ 25.0m = 0.3924 (rad/s)^2

[angular velocity] = √(0.3924) rad/s = 0.63 rad/s

Answer: 0.63 rad/s

Alina [70]

Answer:

Newton's first law of Inertia.

Explanation:

This explains how a magician is able to remove a tablecloth from under dishes and glasses on the table without disturbing them. Because of the mass of the object, it remains in inertia. The Tablecloth, in this trick, is slippery so that it does not have any real friction with glasses and dishes.
