If the effects of atmospheric resistance are accounted for, a freely falling body has an acceleration defined by the equation below where v in m/s and the positive direction is downward. a = 9.81 [1-v2 (10-4 )] (m/s2 ) if the body is released from rest at a very high altitude, determine the body’s terminal or maximum attainable speed (as time approaches infinity). velocity is maximum when acceleration is zero!

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.
