Question
Consider a non - rotating space station in the shape of a long thin uniform rod of mass 1 . 1 2 1 .
Consider a non−rotating space station in the shape of a long thin uniform rod of mass 1.12 x 10^6 kg and length 626 meters. Rocket motors on both ends of the rod are ignited, applying a constant force of F = 2.79 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 1minutes and 28 seconds before shutting off, then how fast will the station be rotating when the engines stop?
a. 4.01 rpm
b. 1.60 rpm
c.5.61 rpm
d.6.73 rpm
