Choose the best coordinate system and find the volume of the solid region bounded by the cylinder requals6, for 0less than or equalszless than or equalsxplusy. the surface is specified using the coordinates that give the simplest description, but the simplest integration may be with respect to different variables. which coordinate system would be best for finding the specified volume?

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
