Question

What is the minimum tangential velocity a space station would need to simulate earth gravity if the radius is 50 meters ?

Answer 1

Explanation:

angular velocity is given by

$w = \sqrt{ \frac{g}{r} }$

$w = \sqrt{ \frac{9.8}{25} }$

w = 0.626

now tangential velocity is

V = rw

= 25 x 0.626

= 15.65 m/s
