Question

All of the questions on this concern a space station, consisting of a long thin uniform rod of mass 4.4 x 10⁶kg and length 171 meters, with two identical uniform hollow spheres, each of mass 1.3 x 10⁶ kg and radius 57 meters, attached at the ends of the rod, as shown below. Note that none of the diagrams shown is drawn to scale!

PART D:

褂欒3 IS 90 degree perspective shift so you're looking straight along the new rotation axis

(d) Let's start again with the station not rotating, and back to its original size, with the rod again at 171 meters long. This time, we would like to get the station rotating at a rate of 0.22 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 1.9 x 10⁶ N, on one of the spherical end modules. How long must these engines fire in order to get the stations angular velocity up to 0.22 rad/s? Answer: __________.___ minutes
