ah~ It looks okay to me, too, so I can't figure out why Mastering Physics won't accept it x___x. Thank you, though, Tim!
edit: /facepalm. You were right to question what the radius was! I was reading incorrectly this whole time and blew the number they gave us to be the diameter, sigh...
Thank you, Tim =).
g = 9.8 m/s2
r = 950m
(Sorry for the confusion.)
Using the formula for centripetal acceleration:
a = v2/r
9.8 = v2/950
v = 96.4883416 m/s
Rotation speed:
c = 2\pir = 5969.926942m
P = c/v = 5969.926942m / 96.4883416m/s = 61.86266592 s
Number of revolutions per day...
Homework Statement
A proposed space station consists of a circular tube that will rotate about its center (like a tubular bicycle tire), as shown in the figure (http://session.masteringphysics.com/problemAsset/1057181/4/GIANCOLI.ch05.p048.jpg). The circle formed by the tube has a radius of...
