Question
(11%) Problem 1: NASA scientists propose using rotating cylindrical craft to simulate gravity while in a weightless environment. Consider such a craft that has a diameter of d = 105 m. ©theexpertta.com * V 50% Part (a) What is the speed v, in meters per second, the craft must rotate at its outer edge to simulate the force of gravity on earth g.

b) in part a) , v = 22.68 m/s
so, ? = v/r = (22.68 m/s)/(52.5 m) = 0.432 rad/s
so f = ?/2? = 0.0687 rev/s = 0.0687X60 rev/min = 4.126 revolutions per minute.
