Carlos uses a rope to pull his car 30 m to a parking lot because it ran out of gas. if carlos exerts 2,000 n of force to pull the rope, and the rope is at an angle of 15° to the road, how much work did he do? round your answer to two significant figures.

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.
