Jets be fired in order to stop the satellites rotation

Reference no: EM13668525

A cylindrical satellite is 1.4m in diameter, with its mass of 940 kg distributed approximately uniformly throughout its volume. The satellite is spinning at 10rpm about its axis but it should be stopped so that the space shuttle crew can make repairs. Two small gas jets, each by a thrust of 20N, are mounted on opposite sides of the satellite and are aimed tangent to the satellite’s surface. How long should the jets be fired in order to stop the satellite’s rotation?
