Question

ads 9 90 degree perspective shift so youre looking straight along the new rotation axis

Mass of rod is 3.8X106

The radius of the sphere is 915m

Let’s start again with the station not rotating, and back to its original size, with the rod again at 915 meters long. This time, we would like to get the station rotating at a rate of 0.09 rad/s, but now about an axis that passes straight down the length of the rod. We will accomplish this by placing a pair of rocket engines as shown, each again with a thrust of 2.8X10-6 N, on one of the spherical end modules. How long must these engines fire in order to get the station’s angular velocity up to 0.09rad/s? Answer: __________.___ minutes
