6. Consider a non-rotating space station in the shape of a long
thin uniform rod of mass 2.87 x 10^6 kg and length 1118 meters.
Rocket motors on both ends of the rod are ignited, applying a
constant force of F = 5.93 x 10^5 N to each end of the rod as shown
in the diagram, causing the station to rotate about its center. If
the motors are left running for 1 minutes and 23 seconds before
shutting off, then how fast will the station be rotating when the
engines stop?
0.88 rpm
2.82 rpm
3.38 rpm
1.76 rpm
